[GNC] Roll up accounts in budget

[Jon Schewe]

I have Expenses:House:Rent and Expenses:House:Maintenance. I input
values for each into my budget. However sometimes I put transactions in
Expenses:House or another sub-account of Expenses:House. 
When I look at my budget report it appears that the actual values
reported sum up the sub-accounts, however the budget value doesn't. Is
there an option somewhere that would allow the budget report to sum up
the budget values of the sub-account so that the report shows how the
rolled up expenses compare with the rolled up budget?

Thanks,
Jon
