beaming within my desired macro beats

If I create a time signature of 13/8, the program automatically makes its own macrobeats and will beam according to that. If I make a time signature of 3+3+3+2+2/8, it will beam the eighth notes how I want them but it leaves that ugly time signature. How do I go about making a nice looking time signature but making it beam a particular way without manually selecting the notes and > beaming > beam together


Type [3+3+3+2+2]/8 in the Time signatures popover
