Lootfilter Item Tier

Any way to filter our low tier rares? I couldn't find a way to match the item base type so far

I would want "Expert Dualstring Bow (Tier 3)" to show and "Expert Dualstring Bow (Tier 2)" to be hidden for example.

You can find my lootfilter at https://github.com/Xeythhhh/poe2EAfilter

Edit: If this is something we can add in the future may I suggest this syntax?

BaseType =~ "Tier 3"
