Hide empty sources and targets in Relationship Matrix

[avzdk]

I can't imagine that its not possible to somewhere hide sources and targets where there no relationships at all. But I can't find the option.

I can find option for highlight source and target elements without relationships but not hiding.

I haven't seen the option built-in, however if you want a view of only related elements then I suspect you could achieve that using a model search to populate each axis with only elements related to the other axis (I assume that you are currently using a package search).
An alternative reason for including all elements might be that it might be important to see that there are no relationships (and if you hide them then you are also unable to create them in the relationship view), but obviously if that's not of concern to you then hiding elements without relationships may be relevant.
