That’s a good catch, @richard. Both the Statements templates and the splitter workflow have a long history with Tiller. Statements was launched nearly 3 years ago as part of the original small business tools release. And I believe an early version of the splitter predates Statements; it was originally deployed as a standalone add-on.
The recent refreshes & integration of both of these tools into the Tiller Labs add-on has brought these old tools into closer contact than any time in their history.
To be honest with you, I hadn’t thought through how they could work together when splits are mixed across transactions types. Do you envision a way that the two concepts can work together in your scenario?

P.S. Glad to hear you are liking (most of 
) the new tools.
