Can MIDI tracks be independent of choke groups

Realizing there are 8 voices and 12 sequencer tracks. Question is for the shared voices, can you use the other sequencer track as an external MIDI track only without choking the opposite shared voice?

Or better yet, can each shared voice independently play external MIDI?

The bongos on pads 7 and 8 for example, can they both play an external MIDI track, or do they choke each other? If the behavior is different when one is playing the internal sound, would be good to know as well.
