Again, Madara's boasting about Perfect Susanoo during his battle against 5 Kage directly implies he used it several times before. He had no chance to use it before this battle as Kabuto's reanimation (since it was the first battle he was mobilised into), neither as an elderly man with the Rinnegan. And since we know that the only Six Paths Chakra Madara had prior to becoming TTJ is the chakra which awakened his Rinnegan, here's a conclusion he could use PS before without it (as well as without the Rinnegan, which means - with EMS).
