Multi-city award search can work fine. Try, for example:

DTW-FLL destination

FLL-MSP destination

MSP-DTW destination

It can yield the sum of award mileage by the three segments, just as it should under present rules.

One thing that doesn't work with multi-city is segment-by-segment searching AAA-BBB + BBB-CCC where one anticipates the resulting fare will be award mileage per the charts for AAA-CCC. The pricing engine doesn't do that reliably, even with a valid routing, carriers, and connection times.
