Standard Segments that can be referenced across successblocs.

Hi Totango Team, 

We would love to be able to create a segment that can be referenced across all SuccessBlocs. We have a standard set of filters we like as a base for all campaigns and we would like to be able to use "Is in segment: Standard Campaign" in all SBs without having to add the Standard Campaign segment to each SB. If we need to change the standard filter, it would be great to just change one segment and it applies to all SBs rather than having to change each manually. 

As we grow this would be very useful!

Thank you! 
Jack
