Modeling Open Wye - Open Delta Transformer

Scenario:
I have a system fed by an Open Wye – Open Delta transformer. There is also a mid tap on one of the secondary windings to achieve 120/240V on the secondary. Is there any way to model this with the SKM Single phase module?

Solution:
Use two single phase transformer with parallet connected. One is A/ab, another is B/bc with midtap.
