This is a small maybe usefull thing i just figured out!
First off you need a stackable seasonal/timed item. I will use Fresh Holly!
What i did was that i had 5x Fresh Holly for 5 days, 2 days remaining. I acquired another 5x Fresh Holly. I Stacked them into 10, the timer reset to 7 days.
This will maybe let you keep the items for how long you like, just that you have to keep restacking them.
This is done by shift-clicking the item then move it to another spot in the bag.
Respond if you don't understand or if i didn't make myself clear enough.
