How do you ACTUALLY whitelist a safe application?

So I whitelisted few processes that I use to modify applications because they are always detected as viruses in the Antivirus. But somehow, whenever I launch them, Bitdefender still blocks and quarantines them every single time. This has become so frustrating as I don't know what more I can do other than completely disabling BD while I'm using these processes which is very inconvenient. 

Is there a better way of telling BD that these processes are safe?
