Being able to pick which line to forecast or forecast multiple lines on a line chart

Being able to pick which line to forecast or forecast multiple lines on a line chart would be very nice.

I am building a release burn-up chart with PowerBI and this is exactly what I would need to compare the forecast of scope increase vs. completed scope.

This would be an absolutely amazing feature.  Right now I'm trying to learn an entirely new set of skills (Python, Holt-Winters algorithm, python integration in Power BI) because my employer requires that a single chart have three lines:
-Actual
-Budget
-Forecast (using Machine Learning)

As it stands, this is going to take me several weeks, whereas if this was implemented, it would take me about 20 minutes.
