I just realized, did Thawne meet Savitar?

Ignoring the finale. In the time travel episode where Barry and Nora go back in time to ask Thawne to make that thing to stop Cicada. Thawne mentions that Savitar was a “much bigger jerk than he ever was”. Not only that, but he refers to Savitar’s face as “pizza face” reffering to the scar on the side of his face. That makes me wonder, had Thawne and Savitar met before? I mean the fact that Thawne mentions the scar on the side of his face, means he literally knows what he looks like, implying that he’s even seen Savitar outside the suit. So I’m curious cause that’s actually some interesting lore, had Thawne ran into him or something before? I mean Thawne is all around the timeline and stuff so anything is possible.
