Can I select an edge or vertex by geo nodes?

I mean in arbitrary mesh I put geo nodes modifiers on or inserted through object ino? Not constructed by nodes itself? I see selection input in mesh to points for example. How can I select a certain edges or edge loop.

Or it’s only working if I constructed the mesh itself by nodes and can select its initial vertex positions by some math range ?

Can I get an edge loop selection through vertex group somehow after object info node?
Like it works with 3d max selection sets in Substance Designer?
