Is there a GC function to separate a multi-split transaction into sepa rate, 2-split transactions?

[Paul W.]

I have multiple bank deposit items showing in a single, multi-split transaction.   
Is there a GC function to separate the multi-split transaction into separate, 2-split transactions?
If not, I would appreciate guidance on how to manually separate the splits, other than re-entering each deposit item as a separate transaction.
