SPSS Macro'sThanks to a great answer on stats.stackexchange.com by Penguin Knight, which should be appreciated despite the knee-jerk negativity they got for it (whether it makes sense to run multiple regressions depends on the situation, and being able to do things within SPSS rather than being forced to use Python might be handy).
Here follows an example derived from that answer.
