Temporary classification by accumulated average lap time

Hello,
In Minibolidos Chamartin (Madrid - Spain) we use PCLC with our BLST track digitized with Slotit Oxigen.
We are happy with all the configuration possibilities of PCLC and we try to apply most of them for our races.
In our club we organize the race by "n" segments depending on the number of pilots, but we make rotations in each segment so that all pilots also perform marshal functions.
This makes that during the race the number of segments done in the race of each pilot is not the same, therefore the classification is always temporarily led by those pilots who have done more segments.
Our request is that the temporary classification is not based on number of laps but on average time per lap of all completed segments.
This makes the temporary ranking closer to the final because it will be led by the fastest drivers regardless of the number of segments done.
If any further clarification is needed, please do not hesitate to ask for it.

Thanks in advance
