Unable to enter correct vector group for three-winding transformer

I have a transformer with vector group: YNyn0d11. The HV-side is solidly grounded, while the MV-winding is ungrounded. I can use a vector group YNyn0d11, but that would give a solidly grounded MV-winding. I tried entering very high RG2 and XG2 values, but those where reverted to 0. If I try to make the transformer YNy0d11 PSS/E refuses to recognize it.

Does anyone know how I can enter the correct values here?

Thanks in advance!
