Summary: Schedule keys should work with Shared Parameters so that the user can used tags where desired.
Description: Schedule keys only work with project parameters (not shared parameters).
Tags only work with Shared Parameters (not project parameters).
This means you cannot tag anything which obtains its data from a Schedule Key.
Not being able to use Schedule keys is a great productivity loss.
This limitation should be removed so that any data can be tagged.
