Any way to get a list of inputs to a metasound?

I’m trying to get a list of the inputs I’ve created for metasound instruments (with the goal to autopopulate a UMG UI from that list) in blueprints.

There doesn’t seem to be a list of those inputs available.

But I’ve noticed that in the editor a metasound in the sequencer creates the lanes automatically, so that data must be somewhere, any way to access it? or to make that available in the future?
