Process tree base rule?

[wilsonlmh]

Feature suggestion: is there any chance to implement a rule filter base on process and it's child process? It's like:

• The rule can be matched by looking at the PID of process's parent(and/or parent of parent...) except launchd
• The rule can also be matched by executable path of process's parent/parent of parent....

I have a bit ObjC experience but I'm not familiar with modern macOS extension API. Maybe I can help but would like to see what you think.
