Suppose I have a program called "Summer Offers". And I tag it with 2 tags: "seasonal" and "loyalty". Now, I am creating my steps within the program, and I want to use the Update Profile step to write down "loyalty" in one of the fields. Today I have to do thism manually. I cannot grab "metadata" from the campaign and use it as a parameter to update profile. It would be super useful to have this as a parameter within the "universe" of the program. Makes programs truly more "multi-channel" by being able to re-use common metadata amongst different channels and actions.
