Adjustable default timeframe progress spotlight

In the current settings the spotlight always takes an inital default timeframe based on the gant chart timescale. This timeframe can then be adjusted by dragging the spotlight window by mouse. However, I would like to be able to control the default timeframe of the spotlight. If for instance my organization always reports 6 weeks ahead, I always want my spotlight to cover these 6 weeks, no matter which timescale I am using.

Now I always have to manually adjust this. It would be nice if the spotlight can be programmed in my saved views as current/date date + x amount of time
