11 - set free refills to see what is in the reagents bank bag

What is the enhancement in mind? How should it look and feel?
Would like for there to be an option to treat the reagents bag in the bank as items on you.
Please provide any additional information below.
If I have 13 lion ink in the reagent bank and open a vendor, free refills should should include the 13 in the reagent bank as items in my bag and buy 7 if I had it set to buy 20 lion ink.
