Automatically sum line items of a module
Is there a way to sum all the line items in a module? Let's say I have 20 line items in a module at the moment and I want to sum it all up in the 21st line item.
(1) Is selecting 20 line items one by one to get the total the only way?
(2) Is there a way to ensure that if a new line item is added somewhere between 1st and 20th line item, it is automatically added to the total formula?
