DAX repeating values

Hello, 

I am creating a forecast by averaging the previous 6 months data. I can get those values no problem. However, I want to repeat next month's forecast for the upcoming months. For example, I would like December 2022 value to repeat for January 2023, February 2023, etc. I tried taking the MAX value from the Incidents Forecast measure, but you cannot use that function on a measure. Any suggestions on how? Thank you!

DAX measures:

Incidents Forecast = 
VAR IncLM = CALCULATE([Incidents Average per Year Month], DATEADD(Dates[Date], -1, MONTH))

VAR Inc2M = CALCULATE([Incidents Average per Year Month], DATEADD(Dates[Date], -2, MONTH))

VAR Inc3M = CALCULATE([Incidents Average per Year Month], DATEADD(Dates[Date], -3, MONTH))

VAR Inc4M = CALCULATE([Incidents Average per Year Month], DATEADD(Dates[Date], -4, MONTH))

VAR Inc5M = CALCULATE([Incidents Average per Year Month], DATEADD(Dates[Date], -5, MONTH))

VAR Inc6M = CALCULATE([Incidents Average per Year Month], DATEADD(Dates[Date], -6, MONTH))

Return

DIVIDE((IncLM+Inc2M+Inc3M+Inc4M+Inc5M+Inc6M+), 6)

Cumulative Forecast = 

IF(ISBLANK([Incidents Average per Year Month]), [Incidents Forecast], [Incidents Average per Year Month])
