Envoyer: work with base directory / subfolder in repository

Hi,

I have a repository where the Laravel backend app lives in a subdirectory called server. I am trying to figure out how to tell Envoyer that the composer commands should be run in this directory or if we can even tell Envoyer to checkout this folder only? Or should I find a way to work with the hooks (new symbolic link or something)?

Thank you for your help!
