Grouping interfaces on Multiple Routers

I am currently evaluating several different Netflow reporting Products.
I like the look and feel of this product (using the on-line demo).

One requirement I have, is to be able to group interfaces from different routers into one report page. I have a fully meshed backbone with 2 routers at each site for redundancy. In order to view all the traffic in & out of a site, I need to be able to select 4 interfaces on 4 different routers (2 for in & 2 for out).
I do not want to select the WAN & LAN interfaces of 2 routers - just the WAN interfaces on the 4 routers (I don't want to see local LAN Multi-cast/broadcast traffic).

A second - nice to have feature, would be alerting when predefined thresholds are exceeded.

Will any of these features be available in the near future?
