Certain deal modifiers can be set to display only when extra items are requested for a deal.
The POS command DEALMODADDEXTRA triggers a pop-up showing deal modifiers marked as Show on Extra Request Only.
On the first request for extra items, any default selections are displayed in the pop-up. If extra items are requested again, you can change your selection.
To create a deal modifier that shows on request only
On the Deal page, in the Lines section:
-
Insert a deal modifier line.
-
Mark the line as Show on Extra Request Only.
