Deleting a lap from a run in Analysis software

[AdrianM]

With the V10 analysis software how do you delete/disable a lap from a run?

When racing on the Brands GP layout they bring you in at the back of the pits so the last lap is never a complete one so it throws off a lot of the auto calculations with that lap in there.

With the AIM software it's very simple but I just can't figure it out for the RT software.

So it's not possible or no-one has ever done it? Seems a very basic function to be missing.
