Suggestion: Allow users to lock items

Hello, real quick suggestion!

Recently I accidentally sold 732 hyper potions to a vendor thinking they were a high-potion. I ended up doing an item restoration request which was resolved, but this got me thinking that it would really be nice to have the ability to lock items so that they could not be sold to a vendor unless unlocked. Destiny 2 has a similar system with gear that prevents your from "desynthing" (in ff terms) gear that may be useful to you. Implementing this feature would reduce the amount of item restoration requests and would help prevent users from making mistakes similar to this.

This sounds like a great idea = ^ . ^ =
