Hi Sakm
Unfortunately not, on a percentage scale, there are very few bikes equipped with the heated seat so not really something we can opt to add as a universal option like heated grips. One of our beta testers made a great video of how he installed heated gear for the wife using a configuration for aux lights 2 - I've included the video on this below:

In your case, this switch will show your wife's gear's heat level and a rotary button on it can be used to adjust the level as you want.
Kind regards and safe travels
