Hello ,
I would like to suggest an idea of mine that I believe could help improve administration of multiple sites with foreman .
IMHO , adding a new var for location could save one the trouble of creating multiple installation medias for different sites , repo etc .
By adding a location var , you could for example , choose in the host's setting it's location and it will add the location to wherever the $location var is used .like:
http://file.$location.<orgname>.com/path
