Custom Classes

Ability to create custom classes within Standings/Relatives, maybe based on car number range or player name. I have recently started racing in a league where there is multiple "classes" within the same race, all in GT3 cars. ioverlay has the ability to import a .csv file that splits the standings into "Elite" & "Pro" classes (or anyother combination) but i am already using and comfortable (and paying for) racelabs and don't want too change. Further to this it would be good if you could have a layout set-up that automatically enables based on racing in a particular league. That way i could have my normal standings/relative and other overlays for official races, but my custom classes when racing within a particular league name
