Hi Sandy,
Not really anything built-in to do this. Victoria's solution is probably the best. The only way I can think of is to create a 'combined' checkbook and then import all of the transactions from both checkbooks as bank transactions into the third. I had a client several years back where we had to do this every month in order to achieve some reporting magic. Once you get it set up, Integration Manager handles this type of thing easily. The source for the integration is the GP tables, so there's no data manipulations necessary (in Excel, etc.). To avoid the whole posting to GL concern, we created a suspense account, called that the combined cash account and then posted both sides of the entries to that suspense account. It was pretty sweet in that we could use the bank rec module. We were using the Electronic Reconcile feature. That's the only time I came across having to combine checkbooks on a regular basis.
Kind regards,
Leslie
