Thanks for this.  It really doesn't get what I'm after.  I want to be able to post to context, but limit and add which modules are associated with each other.  I'm very keen to have events associated with spaces for example and to have events not associated with ads so that posting an ad doesn't give a long list of potential events to include.  

There's probably more thinking from UI perspective as well on this.  If there are a 1000 lives events, do they all show up in the drop down?  for example.

Thank you for the suggestions, we'll consider these improvements in the future:
