Bluetooth MIDI works great except ...

No MIDI thru available on bluetooth so that I can pass program changes thru the Jupiter-X to my Deepmind-12. That only works with USB.

Any ideas on workarounds? I cannot use a plain old USB because 1) I want to be wireless and 2) My phone does not support USB MIDI.[*]

Also, where can I put in a request for bluetooth MIDI-thru to Roland on the next firmware release?
