Dynamically Reference Saved Segments in Discover / Ad Hoc Analysis

[#1]

In a discover project which uses saved segments, changes made to the saved segments via segment manager should automatically update in the project like they do in report builder.

I.e., saved segments in discover projects should be dynamic references rather than copies of the segment.

Also need to maintain dynamic nature when referencing a segment within a segment.

Bump. This is a fantastic idea I was going to post.

The option for dynamic segments would be brilliant. If I make a change to segment A, then segment B which references it should have the option to change or not based on changes in A.
