I wonder if Hyatt has this similar program like Hilton.

I travel alots, I am a diamon on Hilton, My wife & I share the same account for Diamond, Either of us stays in HIlton, we get credit to the same account.

Currently, I am Hyatt Diamond, My wife will be staying at Hyatt next month. I wonder if I can add her to my account, or combine account so she can get Diamond benefits?

Tks
