Did you read the linked thread or just the short version? Just not sure how to answer not knowing that. Some of this will just repeat what is there.
Make 2 shortlists. 20XX Draft, 20XX Draft Board. Use your filters to identify
the "draftable" players. These players are immediately put on the Draft SL. I then move them to the D-Board SL once they are "high" of "very high" and those minimum skills are confirmed.
Once on a SL to scout you simply use multi-select to request reports on the whole list, or the scout list limit, if you have more than 250ish(?). Prioritize the best players. I think I have the pool release 90 days before draft and that is enough time to get everybody to "very high", at least with my scout.
Setup filters to whatever skills you "have" to have to make a guy someone you want. I'll attach my filters screenshot. Note these are all potential and are based on the absolute lowest rating that I think can perform in some way on the MLB level. Your opinion may be different than mine
Build views for whatever you want to see to use with your shortlists. Make them "global" so they can be used anywhere. I have P views, Batter views, and combos.
I sort by overall potential first. Then resort if I want to know about... guys with power, or P stamina, control, intelligence, work rate, etc. etc. etc.
It's only limited by your imagination.
In your views include "short listed". If you do this then on the draft screen you can bring up all of the players but eliminate anyone that is not on your list. IE you can bring up only your shortlist (Draft board SL) and sort and draft straight from it.
From this thread and the one I linked you should get the idea and be able to fine tune it to whatever you want.
