Asset Class Table Time Periods

It would be nice to specify time periods in the Asset Class Table sheet. This would enable modeling a non-typical year, like 2022, and then go back to "normal" in 2023 or 2024 if that is to be your assumption. Currently, you will have to model the bad year, look at the end balances the math produces and then start a new sheet for the "normal" year to get back to normal. I know there is a mid-year update functionality but that leaves you behind the curve and doesn't help prevent a bad future until it may be too late to change course.
