pick focus - exclude objects

[xplorer]

Hello !

please, i was wondering if there could be a feature where you can specify by advance to exclude some objects from the pick focus ...

i know i could disable these objects, then pick focus behind them, then re enable these objects, but i'd still like such feature please.
imagine, for some windows, or camera filter etc, excluded from the objects that the pick focus will see.

i'm not sure i'd be able to write a python script about it.

Thank you.
