Removing resource packs from world files (Bedrock)

There should be a way to remove texture packs from a worlds files in game, currently the only way to do that is by going into the worlds files and deleting it directly from there, which isnt possible on console.
This is quite annoying because that means my survival world on switch is a whopping 40 MB, there should be an option to remove them from the files directly in the game so we dont have to deal with giant file sizes permanently.
