Canadian Forces member posted overseas: how do I file myself as a deemed resident and my spouse as a factual resident, per CRA determination?

As the primary filer and income earner, when I enter Deemed-resident on TurboTax, it automatically takes that for my spouse's profile as well, and does not permit me to enter her in as a factual resident (which she is considered). 

The response to similar question (https://turbotax.community.intuit.ca/questions/1689807-can-i-file-a-joint-return-in-turbo-tax-if-i-a...) doesn't adequately answer the 'how' element of filling out the form given our different residency considerations.

Thank you.
