Edge hints

[slight]

Not sure if this is a feature request or if there's already a way to do this that I'm unaware of.

In the old days I modelled exclusively with tris because poly count was everything, but I have since learned to stop worrying and love the quads. The problem is, I'm exporting low poly character models to Unity, and sometimes the direction a quad is split into tris is very important. So, I want edges for the purposes of making sure the tris sit the right way, but I don't want these edges breaking the edge loops and other quad modelling methods. Is there any way in wings to get best of both worlds here?
