This is not really possible with native QW.
Subtotaling recurring items isn't really a concept QW 'gets' within sections of a quote.
The only way to really do it is to have a script that takes the values of recurring items and puts them in a CustomField on a Subtotal line.
Could you use a summary line?
I didn't think of that! I'll give that a try.
If you use section headers, then you can specifically add Summary Lines that total the recurring values:
I'm using the Quote Default template and need to add some kind of Section Subtotal only for the recurring items. I'm hoping to show this recurring subtotal in each section that has monthly recurring items. I can get the recurring total to show, but not per section.
