Sorry, I really appreciate the help, but I am a little confused or I may have confused situation.

We have 3 environments: dev, staging and production, so dev and staging are seperate. Softgrid is dev. Is it possible to have all 3 subdomains. They would be:

Dev: softgrid.app.vedagrace….
Staging: dev.app.vedagrace…
Production: app.vedagrace….

Sorry for all the question.
