When doing QC on a CD (montage) to save time I like to go to Montage Preference Active Montage and change the default 2 sec to 330 ms. This conveniently puts a visual ‘line’ where the audio should start safely track to track.
This seems to have been moved to someplace else in WL 13 and I can’t seem to see it.
If you are looking for the Default Gap of 2s from what I understand from your first picture, that can be changed by importing more than one file into the montage and have it set to 330ms.
