Orbit POINT of interest AUTOMATIC SWITCH to SUBOBJECT

Hello, I really hope you understand me about my not good english...

Anyway I always use ORBIT POINT OF INTEREST, but sometimes for example in wiereframe or with freeze object, cursor can't see the face and the point of interest appears far from the object...

So I'd like in this case, automatic switch on selected subobject.

If this isn't possible please tell me a code for assign shortcut for ORBIT POINT OF INTEREST and ORBIT SUBOBJECT for do this manually by me. I looked for this in hotkeys editor for assign shortcut, but they're not in the list, there is just ORBIT VIEW MODE...

I use 3DS Max 2022

Thanks
