Using iterative Model Builder outputs in raster calculator

I was trying to create a very large cumulative viewshed using the model builder. So far my model takes multiple observer points and uses them to create lots of outputs. This seems to work fine and I end up with lots of viewshed files in my directory.


The next stage I wanted to do was to add all of those outputs together in raster calculator to make one single cumulative viewshed. Is there a way of automating this in ModelBuilder or is there a better way of achieving this? Better still, is there a way that will end up with a single output, without creating all those interim viewshed files?

Many thanks,
