Forecast Feature - Weights by forecast category

Hi, 

I'd like to triangulate the forecast (by deal stage and by forecast category) and understand if our weighted amounts on the forecast feature are similar or close enough using 2 different weights -  weights on deal stages, and also when moving to the forecast categories section, being able to assign weights based on the forecast category. 

Now the weights in both section are coming only from weights on deal stages. 

So then I'd be able to compare both forecasts and check if the team is being to optimistic in their forecast submissions or not. 

Is there anyway to set up this?

Thanks,

Bruna
