Can ovirt_engine_find_bugs_gerrit be run against changed files, instead of all?

Hey, I noted that ovirt_engine_find_bugs_gerrit eat's a lot of our builders resources. I wondered if the job can be changed to only check changed files, instead of the whole tree? With git you can do git diff --name-only HEAD~1..HEAD to retrieve the changed files between two versions. Greetings fabian
