Add an "owned/accessible" filter to search

Hi Dev team,

I love the search options available for content.  I have one suggestion to improve it further.

Problem:

When I'm searching for things to add to my campaign or my characters, I want to prioritize things I already have access to.  It's incredibly frustrating to dig through the search results only to be met by a paywall.  It's equally frustrating to have to check the boxes for the source material for the things I already own so that I avoid the paywall.

Currently, if you want to search things like "Spells", "Monsters", "Feats", etc. and want to limit your search to sources you own or have access to, you need to check each source individually.  Doing so requires you to remember which sources you own, which is error-prone (might forget some sources, might miss things you didn't know you had access to, might unintentionally include things you don't have access to).

Proposed Solution:

DDB clearly can tell what sources you own.  It would be nice if there was a checkbox or button or something easy like that which you can click to say "only includes sources I have access to".  Ideally, this filter should also include content purchased "à la carte".

I'm not sure if this should be the default or not.  My wallet tells me it wants this to be the default, but I'm sure DDB's sales team wants it not to be the default.  Probably, by enabling this filter by default it would reduce sales because users wouldn't see the content they are missing, thereby not providing them a source of FOMO.  So, maybe not the default.

Regardless, having this filter available would provide a huge quality of life enhancement.  

Thanks!
