Besides reading the full fare rules for every fare, is there a shortcut or any clue in the fare code name that would help ID those fares that allow for multiple transfers?

Seems like everytime I spot a potential MR "great fare" the rules limit the # of transfers to 1. That lack of potential transfers ends up making that seemingly "great fare" into a MR w/ a rather average or even overpriced CPM.

At first I thought the low #of possible transfers was tied to the fare bucket, (T or U = max of 1 transfer) but today I finally came across a U fare that had a max of 2 transfers.

I'm afraid I may be overlooking what at 1st glance would seem to be a higher fare but one that had I been easily able to tell allowed for multiple transfers it could then can be crafted into a multi-leg MR with an better than avg CPM.
