Are there updates on the "RelSci" portion - specifically uploading a list to find relationships?

I feel like this option would be even more helpful if you could somehow tag your organization's contacts (Trustees, staff, etc.) so that the engine could indicate any connections to those that you search. I also would like to know if there are any ways to integrate with Raiser's Edge NXT, We recently made the switch to NXT, and it would be great if we could integrate the two.
