Kind of. I wouldn't say it's a hack but more so just using energy from a charging source like your house to heat the battery versus the car using the battery charge to heat the battery. TBH it's kind of standard operating procedure for EVs and not really fundamentally different than "warming the car up". It's why Tesla for example has a scheduling feature (they really need an ad-hoc one though) where they anticipated that you'd commute, say doing a 9-5, and your car would be heated, battery heated up, etc. by the time you leave for work based on your schedule preferences. Ultimately it's not a huge deal for most of the country (weather-wise) and it'll be yet another item that will improve over time.
