I look for one hour in this forum, to find how to group or ungouping eight allways or sometimes in 4/4
like 2+2+2+2 eight beaming ou 4+4
when i try with right button I allways obtain 1+1+2 or 2+1+1 and after i must rebeam the 1+1
Best regards

Take a look at the options Beam Grouping page of Write > Notation Options and you should find the options you’re looking for.

the magic words was : under beam grouping/Break beams at beat boundaries
