Elderslayers map bulk trade option

It's painful to buy a lot of Elderslayers maps without going to third party trading services. I would love to have an option to buy these maps via the bulk trade search. This could also allow picking the base map type, but I would like to have an option which does not consider the base map type. Running different tilesets is one of the benefits of Elderslayers over Guardians. And there's always Horizon orbs.
