Maestro Slice A>B

Toffy

Maestro (B) Slice A>B Button with a short press puts slice B on A (and with a longer press you synchronize B and A - not really important).

But for me, and certainly many others, it would be important to bring A to B. 

Sometimes it probably works A to B with the A>B button but I can't repeat it or reconstruct how it works. or am I doing something wrong?

Normally, it works in such a way that with the A>B button set the passive slice to the active one. 
Until your Slice A is active and you push A>B, B is set to A.
Until your B is active and you push  A>B, A is set to B. Logical?

You could also simply double click on the A> B button to set  A on B.
Could you please realize that somehow?
