How to model a Tax deferred account that is State tax exempt?(

Hello everyone. I've got a Pralana Online question. I'm a New York State resident and State employee. I've got multiple pre-tax accounts, but one of them (the largest of them) is a 401a (SUNY ORP ) which is classified as NYS pension for tax purposes and as such withdrawals aren't subject to New York State income tax. Is there a way to model this account in Pralana Online? The other pre-tax accounts are taxable upon withdrawal by NYS (with a $20,000 annual deduction for each spouse).

Thanks,

Erik
