How to pass a string into MVC model with AutoMapper - asp.net-mvc

Question

I'm trying to include a csv string involvedBody in a View that is generated using AutoMapper but I can't work out where to map the string to the model.
I assumed it would be in the CreateMap call in the controller or as a .ForMember function in the mapping but I can't get it to work. I need to call the InvolvedBodies function and pass the string into the model before the model becomes an IOrderedEnumerable.
Is this possible or do I need to try something else?
ViewModel
public partial class FamilyInterventionListViewModel
{
public int Id { get; set; }
public int interventionId { get; set; }
public string interventionCategory { get; set; }
public string interventionType { get; set; }
public string outcome { get; set; }
public string achievement { get; set; }
public string involvedBody { get; set; }
public string startDate { get; set; }
public string endDate { get; set; }
public string notes { get; set; }
}
Repository
public string InvolvedBodies(int interventionId)
{
var q = (from body in context.tEntity
where body.tIntervention.Any(b => b.interventionID == interventionId)
select body.entityName
);
var ibcsv = string.Join(",", q.ToArray());
return ibcsv;
}
Controller
public ActionResult InterventionType(int Id, string achievement)
{
var model = GetDisplay(Id)
.Where(m => m.achievement == achievement)
.OrderByDescending(m => m.startDate)
;
return PartialView("_interventionType", model);
}
//Automapper for display model
private IEnumerable<FamilyInterventionListViewModel> GetDisplay(int Id)
{
var list = _repo.Get(Id);
Mapper.CreateMap<tIntervention, FamilyInterventionListViewModel>();
IEnumerable<FamilyInterventionListViewModel> viewModel = Mapper.Map <IEnumerable<tIntervention>, IEnumerable<FamilyInterventionListViewModel>>(list);
return viewModel;
}
Mapping
Mapper.CreateMap<tIntervention, FamilyInterventionListViewModel>()
.ForMember(d => d.Id, o => o.MapFrom(s => s.interventionID))
.ForMember(d => d.interventionCategory, o => o.MapFrom(s => s.tOutcome.tInterventionCategory.InterventionCategory))
.ForMember(d => d.interventionType, o => o.MapFrom(s => s.tInterventionType.interventionType))
.ForMember(d => d.outcome, o => o.MapFrom(s => s.tOutcome.outcome))
.ForMember(d => d.achievement, o => o.MapFrom(s => s.tAchievement.achievement))
.ForMember(d => d.involvedBody, o => o.MapFrom(s => s.tEntity.Select(m => m.entityName)))
;

I've not been able to find a solution to this using Automapper so have reverted to manually mapping the csv string after the model is created using:
foreach (var item in model)
{
item.involvedBody = _repo.InvolvedBodies(item.interventionId);
}
I'd be interested to know if this is deemed to be good practice or if there is some other technique I should be using.
