crescendo followed by decrescendo applied to a round in same bar

Hi all,
As far as I can see there is no way to make a crescendo followed by a decrescendo applied to a round in the same bar (see attached picture) that produces the expected sound.
Yes, I can manipulate the hairpins in order to achieve the graphic representation, but still I do not get the expected sound. (I'm still using MuS 3.6)
Anybody knows of a solution to that?
Thanks,
