Is this avaible yet?Yes, that's correct and even the CAD kernel we use supports that with an advanced reader/writer. Since the advanced reader/writer forces us to use a fat application/document framework from the CAD kernel we only use the simple reader/writer because in FreeCAD we have our own application and document framework. Thus, some time ago I started to implement myself to import colors and labels which already worked with a couple of files but it probably doesn't work very well with the majority of STEP files.
