Yes, it does seem like that is the best way to go.
Otherwise, the user would need to select or create a “series” of named tests. Then I would have to program incremental test numbers for all of those known or unknown series names. Doable, but lots of work for me and the user unless it was done properly.
The, easy and lazy solution, is to name the files with that incremental number.
But, there is a point here. I would like to know how to do that.
