Can multiple users use the dashboard simultaneously and sell different items?

I have two events this weekend, selling two different inventories.  Can I set up multiple screens showing only the items being sold at each location?

I'm assuming you are referring to using the Square POS on an iPad or like device.  you can not have different screens on each iPad, but you can use different tabs of the grid layout.  So tab 1 could be one location and tab 2 could by location 2.  you can have up to 7 pages or tabs of item grids.
