Sensitivity Analysis: allow your lookback period to become a variable itself, and then analyze/optimize predictions for that lookback period variable itself.

We use SA's all the time in my work. One example, we only had 2018 data in our SA, even though our full analysis included 2019 data...this let us see if trends changed year to year. Another example: we made 5 lookback variables, 90 day, 180 day, 365 day, etc...then we analyzed which of these was most relevant to our analysis.
