Using Weighted Sum in Model Builder

I'm making a model where the end result is a weighted sum of 4 reclassified rasters.  I want the user to easily be able to change the weighting of each of the rasters being used, without having to go into the model itself.  Is there a way to set the raster weights as parameters for the model? 
I guess in short I'm wondering how to make the Weight within the weight sum a parameter, the parameters option is completely greyed out when I right click the icon, so it's not working in the usual way I would create a parameter.

Thank you in advance!

I have this same question. Were you able to find a workaround for this?
