filter layers related to xrefs

Hi. I'm new to Draftsight (finally, after some struggle, managed to install it on 64-bit Ubuntu), however I've been using AutoCAD LT for many years. I am hoping to replace A...CAD with DraftSight in my work and not have to use Virtual Windows Machine anymore. However, after using A-Cad LT for years I am accustomed to using certain commands and certain ways of proceeding with my drawings.

One thing I'm not able to find (there are more, but this annoys me most at this time) is how to set a layer filter which would automatically filter out all layers related to all external reference drawings used in my current drawing. Or, list ONLY the layers belonging to xrefs (this is easy, "reverse the filter").

Despite finding the DraftSight's Layer Manager a "little buggy", I understand that I could (at least in theory -the practice is "buggy") create a filter containing ONLY the layers belonging to xrefs by adding manually each such layer to the filter description. But I'm used to having a filter like "All xref related layers" or "All non-xref layers" which would AUTOMATICALLY contain all xref related layer right after loading an xref, without manual adding individual layers every time I add a new xref or change an xref for a new one containing different set of layers.

Is this possible inDraftsight ? How can I do this ? Thanks for any answers...
