I don't know if this is the right terminology - but my interest income in my Fidelity HSA is "swept" to a MMF. When I download transactions, though, the IntInc transactions are left in cash and I have to manually enter this "sweep" to the MMF.
There's a field on the Income transaction type for Transfer account - is there any way to transfer, on that IntInc transaction, to a specific SECURITY within the SAME account?
