How to lengthen dynamics hairpin

[Bertalan Fodor]

I would like to lengthen the dynamics hairpin in this case:

d16\> dis\!

Setting minimum-length is not good, because it makes bigger space 
between the two notes.

The problem is essentially that the end of the decrescendo is always 
attached to the left side of the note and not the right side (which 
would be better in this case).

What is the solution?

Thanks,

Bert
