No of products in Container [PickMaster 3]

Is there a way to read out how many items that are placed in a container without having to write code?
Right now I figure it out by reading how many is left in the container and subtract that from the high level of products.But for my case it’s not really optimal because I have to compare against a low and high count of products so right now I have to define a container which contains exactly the high level, and in some cases that means that the last layer isn’t always a complete layer.

No, there is no easy way.
