As a workaround I mapped “center position"to a yoke button, and then I use VoiceAttack profile to actually say “move seat forward” or “move seat up”, and that does it. Normally only one or maximum 2 commands are needed to get to the right position. What also helps is I lean back in my chear, then hit “center” button, then seat normally. That mostly gets me to the correct position (it’s too far by default for my taste”). After that I only sometimes need to say, for example, “move seat up” once, or “move seat forward” once to get to the ideal position.
