Description - Allow for creating audiences in the library from other previously saved audience library audiences.
Why is this feature important to you - We do a lot of geo targeting and we have custom geo audiences set up for many markets. When we need to combine more that limit will allow (for targeting or for exclusion) we have to basically rebuild them all in one new audience. What a beat down.
How would you like the feature to work - When building a new audience in the audience Library allow for the choice of 'rules-based' or 'existing audience'. This would also be great for combining multiple shared AAM audiences or you could have a third option of 'hybrid' that would allow you to combine rules-based logic with existing audiences to create a new audience.
