SEPM add local Hash exception capability

Our company writes a lot of in-house software that's only used in-house. I need a way to add exceptions based on the Hash values the programmers send me instead of leaving entire directories un-protected. Each programmer has their own style of originating their code and getting them to all use the same directories is an impossibility.

Submitting every recompilation to Symantec's false positive site and waiting for it to be exempted is not functional.

I need a quick way to add an exemption based solely on the files Hash/Name.

Thank you,
