Diablosport i3 - Can I calibrate speedometer with it?

[Down the Tubes]

I just installed an unlocked PCM in my 2018 Power Wagon and uploaded the Diablosport tune through my i3.
I can't for the life of me figure out how to calibrate the speedometer with the i3.
Is this a function that the i3 can do?

I have previously used a Hypertech calibrator, but it does not work with the new PCM.

Diablosport says that this option is not available for the Power Wagon.
Time to get AlfaOBD!

Got any recommendations?
I bought a cheap Samsung tablet and AlfaOBD, but just got the bypass cable (Diablosport cable is 6' long.....kind of a pain) yesterday and haven't had time to install it.
