Find valid control mappings for a specific aircraft

How can I find out which control mappings are valid (resp. what’s the name in the controls-options-menu) for a specific aircraft.

e.g. I wanted to map the “Aux boost bump on/off” for the TBM930, but could not find anything in the controls-menu named “boost” or “boost bump”.

My question is gerneral (not just related to the Aux boost bump in the TBM):

How can I find out which control-mapping (in the options-menu) are supported by a given aircraft?
How can I find out what’s the name in the control-mapping-options for a specific aircraft cockpit-button?

ps: just found that this is pretty much a duplicate of Cockpit tooltips should show actual control names (which is not answered)

Nobody knows an answer?
