There is scope for changing the colours of the displayed outlines by including the layer number(?) in the header of the outline .out file - then setting this colour either to the background colour or a contrasting colour using Preferences and saving (exporting) that scheme.
Somebody on the forum discussed the .out header and I did have a quick play and changed the colour of my Birmingham TMA, but I haven't looked into this further. It might be a fix, but a very time consuming one to set up.
I hate to admit it, but BS does handle the selection of outlines well and in a flexible way :-0
