No. One can create one's own pad shapes in Pulsonix, but it costs a lot
more. You could always edit the Gerber file, but this can be tricky. I had a
look at the SOT-89 footprint (Pulsonix includes it); it uses rectangular
pads, so I can't see the problem.

You'll have to use a narrowed track segment to connect to the pad, if you
don't like the 'dome'.
