split deposit in bank feed

I have a new QBs headache I am hoping there is an easier work around. We currently have multiple AR set up for different years for tuition. The vast majority of our money comes through an organization called FACTs that allows us to invoice and track all the money. For this reason, when we set up the accounts in QBs we use the same customer (FACTs) and just import the money through that "customer." The challenge is when we get a deposit from 2 different ARs because they are from 2 different years. Is there an easy way to split the deposit in FB to allot money to each account? I know when I have split transactions it is usually from a matched JE BUT I cannot create a JE with 2 ARs. So I am hoping there is an easier work around than putting all the money in one AR and moving it afterwards, but fear that may be the only option.
