Compendium Source Selection Defaults

I would like to see the default for new compendium sources to be " Not Available " rather than " Available for those who own ". Or at least an option to choose this default. I am increasingly frustrated to see the myriad of options growing in 5e (over 240 sources now), and they're always showing in game, even in the Charactermancer, unless I go into all my Game Settings for each campaign and change the newly available sources from "Available for those who own" to "Not Available". I don't need a sales pitch showing in my game that I'm paying a Subscription for, and it annoys me that it is foisted upon me. New sources are added frequently enough that I have to go in a check these sources every other week in every game. It's just too much. I have better things to do.

+1. So much this. I would also like to add that the only compendiums that show up as default are ones that I, as GM, own. Or, be able to filter what is shown as 'owned' by me. There is never a time when I think to purchase a compendium while in the compendium sharing screen.

+1, and I'd +10 this if I could.  This is SOOO annoying.  I have a campaign with a specific design.  I don't need or want random stuff I buy for other games, or a player buys for their own use, showing up in it. Or worse, free stuff someone thought would be useful.  Right now I have to go through the list periodically and prune it. There are certainly games that don't need that level of control.  And I'm fine with it being optional. But give us the option to set a fixed list and stick to it.
