I have searched both tricky treats and limited duration.
If you have tricky treats with an hour or less than a day duration you can extend their duration by stacking them with a higher duration stack of tricky treats.
i.e. I have tricky treat stack (A) with 6 hours left on them and I have another stack (B) with a full duration [1 Day].
I split stack B up into parts (say 10) then do the same to stack A
I then add one of the stack A parts to a stack B part and the duration will be that of the stack with the higher duration.
I have only tried this with smaller Stack A's then B but it should still work with larger Stack A's aswell.
