Strymon Looper Mode Display

I have a bank programmed to control the Strymon Timeline Looper function, It works great. I have

Record - does record/overdub like TL button A
Play - same as B button
Stop - same as TAP
Fade Out - very cool, using the CC waveform generator

Expression 1 as loop volume

What I can’t figure out how to do is enable Looper Mode display on the timeline on entry to the bank. You can control the TAB switch with CC81 (0 is up, 127 is down) but there is no way to generate a timed down then up from the bank enter and exit messages.
