lap gain/loss vs best lap of session?

Hi guys,
New to MoTeC, I have an ADL w/M800 ECU. I see running lap gain/loss calculation is by default versus a reference lap that is input to the dash logger prior to going on track. My question is can I set up lap gain/loss to reference the current fastest lap of the ongoing on-track session instead? The logger records lap minimum time so it would seem it should be possible to do a maths channel and display running lap gain/loss against that?
Appreciate any help, I'm slowly learning how to use MoTeC. My only other experience with data is AIM EVO4 and steering wheel display.
Cheers,
Mikey
