Allow searching Blighted Maps by tier in the Bulk Trade

Currently you must manually select each and every map you want for bulk trading Blighted maps. I mostly care about tier rather than base type, but the bulk trade only lets you select 10 items at a time. With there being 303 Blighted maps on the bulk trade, it makes it impossible to select a reasonable portion at a time. I prefer to use the "Group by Seller" feature since most sellers will have a large amount overall but relatively few of any individual base type. That feature only works with items in the active trade though, which compounds with the previous issue meaning it's not particularly useful when buying Blighted maps.

My suggestion is to implement a way to search by the Blighted map's tier in bulk trade.

I'm trying to complete the Bizarre Blights "Complete Tier 14 or higher Blighted Maps with at least 80% Item Quantity x10". Really wish I could just bulk search these on trade instead of having to select 10 specific maps.
