61 trading partner selection on processing rules

I know this is old news but I’d like some feedback on what everyone else does.

In 6.1 when editing the partners in a processing rule, how do you deal with the long load time of the partners and the fact that your list might be over 1 or 2 pages long?

Any good work arounds to speed this up or make it easier?

Has anyone used a flow service to add partners to one or the other side of a processing rule, instead of editing it in TN?
