Is your feature request related to a problem? Please describe.
The dehydration mod is apart of a modpack I am developing for 1.20.1. The usage of storing "Purified Water" would be extremely beneficial but does not currently work.

Describe the solution you'd like
Simply allow dehydration.purified_water into the tanks of the backpacks.

Describe alternatives you've considered
I could download another mod I guess, but I really enjoy Travelers Backpacks.

Additional context
The image below showcases that the bucket will not go into this slot.

every modded fluid can be put in tanks if it's registered as fluid and bucket as fluid handler. mod author needs to make changes
