Forecasting with current month information

Hi, 

I have been using the forecasting feature in PBI now for a little while and would like to know if there is a way to adjust the current month's forecast based on what has happened so far in the month?

I have three years worth of historical data in the forecast, once I include 'month so far' data, it thinks thats my actuals. Is there anyway to tell power bi that its in month rather than actual?

Thanks!
