Master Palette , Time signature : possibility of setting how rest are grouped

Hi every body,

Silence in x/8 time signature aren't grouped as espected as explained here http://musescore.org/en/node/4867

Could it be possible (as a future workaround if rest beaming can't be resolved) to be able to also set default rest "grouping" (in could be as a way we enter note, as rythme done with keyboard

That could be also usefull for "unusual" time signature for when they are regular (5/8 in 3+2 or 7/8 in 2+2+3 for examples)

Thank you
(it can't be for 2.0 but for another time)
