This is being worked on as part of a much larger project that is not owned by the Launch team.  I'm archiving the idea so we are not tracking it as part of the Launch forum, but keep your ears open for more news.

First releasable chunk of this is in QE now (and it's sweet) and we're planning on releasing it next week.

Current plan is to have this done by the 2019 US Summit.

First rev of this has been released.  You can now copy your rules.  Next iteration will allow you to copy them to another property, and after that we'll work on bulk operations.

Something like this is an idea that we're working on for next year, not sure exactly how it would work yet, but totally recognize the need for a central place to modify rule components and data elements that can be used by multiple properties and managed in one place.

I agree that having a deletion be a change that needs to be published like any other change would be the simplest way to manage that.  The technical guts of accomplishing that (states of being marked for deletion without actually being deleted) is more than what we wanted to take on for a first phas...

It's a good idea and one that shouldn't be too hard.  I've got the front-end dev team in the middle of a couple other projects, but we'll try to pick this one up afterwards.

Can you dream about it? Sure =)Can I guarantee it? Unfortunately no.  We will first work on rule copy (within a property), and the ability to copy ruls, data elements, and extensions across properties.  Then we'll work on copying the whole property.

Added a feature request in the Analytics queue.

I've seen some functional prototypes from the dev team, not pretty yet, but working.  We'd like to productize this before the end of the year.
