Segment filter in RCE

We found that there is no segment filter in RCE that you can make available for Custom Field Sync. Therefore, the way a user must get around this is by essentially making the fields that the segment rules are based off of available to RCE and manually adding those fields as filters to the RCE reports. This is a lot more manual work versus the ability to have a built-in Segment filter in RCE. Please vote!
