Not that I have found. It seems to default back to being told what trailer, in a couple of hours, it seems to be tied into the tow mode. When the tow mode resorts back to normal, the trailering app needs to be told what trailer is hooked up.
Now, if'n I hookup to a trailer and before moving, the app will have the last used trailer highlighted to tap on. Could be months since the last time truck was hooked up to a trailer with a pigtail.
These are first gen T1's.
