Money in as income, money out as expense - how do I tie the two together?

I do the accounting for a Cub Scout Pack. I have money that comes in which is categorized as an income account. Then I create an expense account when money goes out. How do I tie the two together.

For example, we have an event. I collect money for that event, that money goes into an income account.
We pay the vendor for that event and when the money goes out I create an expense account.

I want one line item on the report that shows the money in, then the money out, for the same account. Versus seeing the money in on the income side, then the money out on the expense side.
