Option to Receive Back-in-Stock Notifications for Entire Product Categories

Hi HobbyKing team,

I would love to see an option that allows customers to subscribe to back-in-stock notifications for an entire product category, not just individual items.

For example, if I'm looking for FPV parts, LiPo batteries, or RC plane accessories, I often check several similar products because many are out of stock. It would be much more convenient to receive a notification when any product in a selected category becomes available instead of subscribing to each item separately.

This feature could save customers time, encourage repeat visits, and make it easier to discover alternative products that are back in stock.

Would anyone else find this useful? I'd be interested to hear your thoughts.
