[GNC] Question about billing

[C H]

Hello,

I downloaded GNUcash a couple weeks ago and I've been gradually entering
past data, and there's something I keep running into that I'm hoping
someone here can give me advice about. When I create bills, I frequently
want some expenses to count to one period, and some to count to another.
For example, when I enter a credit card bill, statements are generated
halfway through the month. Half of expenses might be from May and the other
half from June. The only way I've found to make expenses match the right
period is to create two invoices. It feels like there must be a better way.

I tried entering each transaction through journal entries, but it was
cumbersome, prone to mistakes, and then I lost the ability to view
information about my credit card bills on the vendor report page.

Is there an easier way to match expenses to the right period?

Thanks
