Feature Request: More control over rebuilds in Digital Ocean App

It would be helpful if there was more control over when DO App rebuilt.

I would like to change environment variables without triggering a rebuild and the reason is:

If I make changes to my code base which includes adding new environment variables then I go to DO and add the environment variables. This triggers a build but it is not pulling the new code base from github during this rebuild. So once that build is done then I have to rebuild again so that it rebuilds with the new version on github.

Long story short I have to do two rebuilds if I change something that requires adding environment variables.

Another option would be to have a setting that disables auto rebuild on environment variable changes or to at least cancel a rebuild that is in progress.
