(Solution in any language also welcome for Power Query Challenges)

Calculate Running Total for each dealer.
The running total is calculated within a bracket of 3 months only. After 3 months bracket, running total will reset.
For Dealer - 1-Dec-2021 and 20-Jan-2022 are within 3 months bracket. But next date 25-Mar-2022 is not within 3 months of 1-Dec-2021, hence Running Total resets here. Once running total resets, next bracket of 3 months start. Similarly, 2-Aug-22 is beyond 3 months from 25-Mar-22, hence running total will reset here also.
Remember 3 months is not equal to 90 days.
