Up Next List Option "Watching Only" Question❓

I’m late to the party … just saw that there are options for the Up Next List.
At the top I only care to see Watching Only which is great that I can set that.

Will my Watching Only list be able to use the item count of the removed Recently Added Only items❓

I’m asking because I want to be able to have a much further reaching Watching list then is currently possible with Infuse. It’s one of the most missed features in my family since we switched from Plex to Infuse. Not sure why the item count is capped but a user set number would be soooooo helpful!
