ECSL - Add transaction date to help when ECSL quarter different to VAT quarter

Hi
I have to do an ECSL but the quarter is different to the VAT quarter (as I suspect it is for a lot of people).
I can see the client totals for the VAT quarter when I click on “view ECSL” on the VAT return, but it would be good to see the relevant date for ECSL purposes (and maybe the individual client invoice totals) so that I can use this data in my ECSL here:


The alternative is to keep a separate list of sales in excel, which to be honest is what I was trying to get away from by using QF.
Or, get QF to create an ECSL for a specified period for me?

Many thanks!
