Not really? Additional Recipe Requested.

Describe the solution you'd like
I'd like to be able to Upgrade the Standard Leather Backpack without the Glass to the one with the Glass. That recipe doesn't seem to be in the version I'm using. MC 1.21.5, NeoFroge 21.5.56. Travelers Backpack 10.5.0 (Release).

Describe alternatives you've considered
Creating a Datapack to add the recipe. But the 2 Backpacks seem to have the same ID "travelersbackpack:standard" on both versions.

Additional context
Providing screenshots here to show what I mean, in case I'm wrong with terminology.

You have to craft tanks upgrade and apply it in any empty slot on the right side of backpack inventory. Tanks are visual representation of the tanks upgrade.
