That's awesome. Could you share how you are mapping it?
I don't think Geist with the TFP has that ability as it requires scripting and bi-directional midi (e.g. Bitwig and Live) but you can map retro record to a button. This will allow you to play the sequence on the TFP then hit one button and have it stored instantly on the pattern lane.
I messed with this as well so am happy to help if I can.
