Show only Inherit relations in diagram - how?

[mbc]

I would like to hide all relations except inheritance (generalizations) in a diagram. I know of the Show/hide relations feature, where I can check or uncheck each relation individually, but i find it too much of a hassle to do this every time I add another type of association in another diagram.

Is there a way to enable only generalization relations in a diagram? If not, this is a feature request!
It might be a useful feature for other types of relations also.
