How about changing to use it with an other software like Traffik?
Using traffik to proxy your traffic and handle your certificates of let's-encrypt. So you have one container who does it both and you can fire up as many docker container with traffik labels to route with tls certificate to new subdomains etc.

Traffik handle multiple domains: https://plexguide.com/threads/howto-configure-traefik-to-handle-multiple-domain-names.3420/
Or the traffik doc: https://docs.traefik.io/v2.2/routing/routers/#tls
