I am not sure how well this works, but in the style editor there is a check box in the MISC settings for "Waltz".

The style editor is old, so it probably works best for MIDI styles, and I do remember seeing somewhere that the patterns used will adapt to 3/4 or 4/4.

But RealStyles, I am sure, need the Real Tracks to match the time signature - or maybe not.
