Issue with Buying Vendor Shop Items

I've noticed a common issue where you want to buy an item in the shop but the items cost in gold is very high. It would normally be a farmable amount of gold but the item inventory will get rerolled before you accumulate enough gold to purchase it. Could you introduce a way of deferring or marking an item so that it isn't rerolled on a vendor refresh? I currently feel forced to hoard gold while leveling to afford cool items when they pop up which feels kinda bad. I wish i could just save up and buy the cool thing the vendors are offering without it rerolling
