This is not possible, and the value would change based on selections, data reloads, the context of the object the measure was used in, etc. You would need the entire data model to pull the measure, which is possible using the Binary statement, but that doesn't sound like what you're trying to do.
If you'd like to have one app store a value for another, you would typically do this in the script and store it to a QVD file or similar.
