accents (lsf, usf) in M-Tx/PMX

[Alexander V. Voinov]

Hi and Happy New Year, wherever applicable, All!

How could I do $Subject?! Really I can, modifying one of the hints I got
here for the cautionary accidentals. But in Choral music flags on the
notes are upwards for the upper voice and downwards for the lower voice
on the same staff. In these cases accent symbols (>) intersect flags.
And I see no parameter which would allow to raise them or lower above or
below the entire note with its flag.

Thank you in advance

Alexander
