Hi and welcome to the forum,
The only way, how to transfer it to the only one field is to use the MIDI Patch for the instrument, which describes, which instrument/sound sits at witch Program Change, and Bank Select MSB & LSB.
If this is not the case, you have to use both fields: Program and Bank Selector (what is the Bank MSB and LSB at once).
- The Bank Selector value 0-127 means MIDI CC0 = 0 and MIDI CC32 = 0-127.
- Bank Selector value 128 = MIDI CC0 = 1 and MIDI CC32 = 0.
- Bank Selector value 129 = MIDI CC0 = 1 and MIDI CC32 = 1.
- Bank Selector value 130 = MIDI CC0 = 1 and MIDI CC32 = 2.
- etc.
