I would like to request a feature for Economy.

I really like economy.conf claim-cost-per-block feature that adds ton of player progression steps to vanilla game.
But right now RedProtect doesn't have a automated process to give spent coins back to player. I know that BuyRegion exist buy to my knowledge it lacks "self sell" option.

claim-cost-per-block already uses eco to withdraw for player while claiming, so why not have a give coins to, based on claim area size and cost-per-block value.
I know my request has a big flaw, what happens if the claim has two or more leaders.
