Replicate Behavior of Somfy 2 Button Controller -Move Shades on Press, Stop on Press

TL;DR - Looking to have a remote that raises/lowers shades when I press a button, and stops movement when I press again.

For years I've had Somfy blinds in a couple of rooms, and these are controlled mostly by various automations in Hubitat, however, also by the remotes that they came with (which also show in Hubitat). These remotes are Somfy 2 Button Controllers, and when you press up, the shades go up - until all the way up OR you press the button again. The same is true for putting them down.
This makes it really easy to put the shades in the exact spot you want. The problem is I can't figure out how to replicate this behavior with any other remote. For example, I have an Ikea Trafri I'd love to use in the same way - but while I could have a button that moves the blinds, it's an open/close situation - I don't have a way I've figured out to stop the movement on demand.

Is there a trick I'm not thinking of here?
