The meter mentioned before, 12 = 3+2+2+3+2 with quadruplets, is very  
popular in the historical region of Macedonia, on both the Macedonian  
and the Greek side (though a lot seems to play it in 16 = 4+2+3+4+3).  
There is a music example here, listening for especially at about time  
2:00 and after.

So here, to get subbeaming expressing the musical pattern, one might  
want to write the meter as
  ((4:3)(2+2) + (2 + 2)) + ((4:3)(2+2) + 2) * 1/16

It is possible to sometimes have quadruplets on the 3s, and sometimes  
not. For example, in the original version of Makedonsko Devojce, which  
is in 7 = 3+2+2. So one might want ot have more patterns:
  3+(2+2) * 1/16
  (4:3)(2+2) + (2+2) * 1/16

These metric patterns are then quite similar for other beaming  
patterns, only that the latter can be applied to other than whole  
measures.
