resend control-surface feedback messages?

I’m using a BCR2000 and I’ve programmed a sequence of presets to behave as ‘pages’ of channel strips. The BCR ignores feedback for strips which aren’t in the ‘current’ page - so my surface is rarely in sync with Ardour.

Under 0.99.x there used to be a key-binding to resync the surface, but I can’t find the equivalent in Ardour 2.0.2.
