Solution:
Bulk Insert (Like MeshParts) should be supported (for Decals), Keeping the File Name.
Insufficient workaround: Select a part and drag decal onto it preserves name, but only inserts one at a time.
Double clicking just names it Decal, for no good reason.
Adding onto this: You should be able to click and drag assets into the explorer (or onto a part) to insert them. Would definitely improve developer experience!
Not only does it apply to inserting, it also applies to copy pasting IDs, I got rbxassetid://13419590318 instead of having multiple in one clipboard, so I believe this is a good idea
Support, I’ve found this extremely annoying in the past having to insert a ton of decals individually. A “Insert selected” feature would be great
