If in your center you have created several cash drawers for the different points of sale and if each one of the products that are sold are different, it can be customized so that, depending on the cash drawer that you have open, the products of quick sale may be one or another.

You have to enter through the menu:

We have the list of all the products created in the center. The POS's quick selling products are those of the item type.
These products must have the check next to the Quick Sale field unchecked and in the Quick Sale by cash drawers section add the cash drawer / s in which you want it to appear.
