Remember customer in table

The app is working well and we were able to do all the customizations required except one. The pos will be used in restaurant mode. How can we make it so that the table remembers what customer was assigned to it.

Example: I add customer and add items to table. Then i add another customer to another table and add items there. When i return to the first table, its the second customer by default. We want it to be so that it remembers the original customer.

Thank you for your help.
