TPMS-which works for mh & toad, then toad only?

I'm not aware of any TPMS that allows dropping the RV readings leaving only the toad to display. The TST at least, can do the reverse though, by dropping the toad readings when the toad is not brought along. In my previous toad, I installed a second TST monitor that was only programmed with the toad sensors, and just kept it in the toad. My current toad has the factory installed TPMS, so I have no need for the second display now.
