This seems odd to me.

What is the advantage of placing your indicator in your ball bag after every pitch? To me it seems like it wastes time. (I guess that you use 2 ball bags and place the indicator in your left bag). I do not want to re-start the "old" topic of not using an indicator (great for those who are "good" enough to not use one-even though I see MLB PU's using one) as I always use an indicator. To me, your habit would also seem "fidgety". I use a plastic indicator and don't seem to "scar" my mask.
Maybe you need to listen to the "big Don" to obtain your desired umpire advancement.
Anywhy JMO.
Good fortune in your quest.
