How to arrange subsystem ports?

[fzs]

Hi,
i have a large simulink/simmechanics model. Is it possible to arrange ports on a subsystem block, so that I don't have so many crossing lines? Right now, it's very confusing.
Or is there even a way to automatically arrange the blocks and ports?
Thanks in advance.

okay, I think I found part of the answer. I used PMC-ports in which I can set the position in the parent subsystem.
But I still don't know how I influence the order in which they appear on each site.
Or is there a possibility to optimise the arrangement of blocks, ports and signals?
