Today I needed to assign the same texture to multiple items, I thought that by just selecting multiple Items I'd be able to give all of those items the same texture, but it seems that it is not the case.
I think this would be a great QoL implementation.

* A [Customize] button should be displayed for compatible selected items (i.e. items that have a texture field)
* Expected behavior: All items will load the same texture file, from a single pop-up message that will update multiple items sequentially.
