That caracteristic is one of SPPA too.
Yes, the point of the method I mentioned was not only that it worked in single-member districts, but that it worked on lone mark plurality ballots.
As an aside, it seems that SPPA produces a strong incentive to "bullet vote" the candidate from your favorite party. As such, it actually seems fairly similar in result to the method I mentioned.
