Weird Situation - Need to Match Something in Split Category

So when I am balancing our budget at the end of the month there are sometimes you know money is coming and it hasn't come yet. In order to not go into the next month in the red I will manually enter the money that is expected in the next couple of days and then match it with the transaction when it comes in. However, this time I was waiting for a reimbursement from work for a seminar I took. I did the usual which is manually enter the money coming back from work but when my check came in it included the amount I was waiting for. Now I split the transaction and placed the extra income in "Awaiting Reimbursement" which is where that type of transaction goes, but now I can't match that portion of money with my manual entry.

So if anyone has some suggestions I'm all ears.
