Allow multiple domains for target

Some of us need to deploy to hosts but allow multiple domains for white-labelling purposes. It is already possible with some tweaks to the docker-compose file as described here:

The problem is that every time a change is made to the target, the docker-compose file is rebuilt and the changes are lost which is highly frustrating and time-consuming to resolve (as well as the raising the likelihood of deploying with the reset version of the file)

Could it be possible to create a list of domains for the target which Wappler uses to create the docker-compose file?

At a minimum, is there a way of making the changes so they persist?
