cannot find report

[Paul de Vries]

I need a transaction report for a given period with total over sub-accounts, e.g.

999 main account
	21 oct transaction $ 1.00
999 total for apr $ 1.00
999-1 sub account
	22 oct transaction $ 2.00
999-1 total for apr $ 2.00
total for main + sub account $ 3.00 <-- this is the line i'm looking for.

i remember vagely that i did something like this in the past but i cannot find it anymore.
