With the incoming 3.29 league, we will be able to transfer a defining mod from a unique item to another unique, the twist being that we can't choose the final unique; it's randomly pulled from the core unique drop pool. When using PoB, we can filter uniques depending on if they're a vendor recipe, a boss item, a corruption, but we can't do the opposite: filter to only get uniques that aren't any of those, aka unique from the core drop pool. This would be especially useful in combination with the "Sort by" feature, as it would allow searching for the next best unique in specific builds much easier (for example, the next best shield to replace Aegis aurora).
Describe the solution you'd like
I would like a new filter to be added here, and that by selecting it we look for unique items that are from the core drop pool (as a reminder: core drop pool means items that are always obtainable, that you can get doing pretty much anything).
Describe alternatives you've considered
I'm pretty sure there's currently no way to achieve this, since we can't combine filters right now. As an alternative, being able to whitelist or blacklist different filters would be great (similar to PoE ninja, where you can whitelist or blacklist items/nodes but with unique items filters instead), but considering the actual system implemented, I do believe that my previous solution will be much easier to implement
Additional context
Here's a small paint of the UI evolution to better image what I'm talking about.
