Forming 10 Tuplets

I am trying to recreate part of the Lark Ascending (written in 6/8) where theres a section of 10 tuplets over the interval of a dotted quarter note.

Having limited success (it should look like the bottom left in pink which is the original Vaughan Williams). The top lines are where Ive been making various attempts and the closest Ive got is the other pink box box above the original ...but the beam is for 1/8th notes rather than 32nd. Is there a style override I can use to get three lines ...or any other suggestion to create the same as the original? Any help gratefully received!
