Pretty sure not. The filter is almost there to allow you to at least type something in, but not quite. I tend to use the Export/Import rules to do a bunch of these. it's not just Config Items, but all of those lists in the agreement rules behave list this. Sounds like an enhancment request to me Peter :-) Go on, you know you want to.
Thanks, Dave, I thought that might be the case. I'll get onto the enhancement request!
