Note Grouping for 5/8 -7/8 -9/8 Rhythims


I’ve tried to change the notation using Beam and Note grouping for 5/8 time signature, but no luck.
I like the group the 5-8 rhythm as 1,2+1,2,3 (8th long length) See attached pic.
Is there any custom note grouping option?

I’ve also included Dorico file

Thanks in advance

Have you tried inputting the time signature as ‘[2+3]/8’?

Thank you fkretlow.
Additive time signature worked. However the signature is showing 2+3/8 instead 5/8.

Frankie, the square brackets are important. Try [2+3]/8

Thank you, much appreciated.
