Subharmonicon permanent XOR mode?

I find the Subharmonicon more inspiring in XOR mode, but I often want to use it without a computer nearby so I’m unable to send it a midi signal to turn it on. It’s very annoying that XOR mode is not persisted across restarts.

Is there a way to make it permanent somehow? For example with a sysex file. Thanks!

Or even better, a firmware update that would allow you to change this on the front panel!

Yeah, that would be even better. I’m crossing my fingers for that
