Yes, since around 2009ish. Pass the flag "-mt" on the command line. You'll see a line in the log like this:

MT: evaluation of 385/3124 sub-devices will be parallelized

When it works, it's great. Unfortunately how it decides which sub-devices are eligible is extremely unpredictable, and if only a few of them get parallelized then you don't get any performance boost (in fact, it actually degrades performance).

So, it works, but it's unreliable.
