Mortgage payments in Income/Expense report?

[Dan Rawson]

I've set up my mortgage as a liability, and the checks are split to the liability, 
property tax, and interest.  I'd like to be able to run an Income/Expense report that ALSO 
includes the transfers to the liability (let's face it, that's an "expense" :-), but the 
Liability accounts aren't available to select when doing the income/expense reports.

The alternative would be using the account summary, but I can't do a date range limit on 
that report.

Do I have to write a custom report to to do this?

Thanks!

Dan
