I hope to get a Premiere version up at some point but unfortunately haven't gotten around to it.
That said, I actually use it in Premiere all the time via dynamic link since I'm generally creating all my graphics in After Effects anyways...
What I do is create an AE composition to match my PR sequence dimensions and framerate. I'll then auto-generate my slate within that comp. Back in Premiere, I then select: File>Adobe Dynamic Link>Import After Effect Composition and select the slate comp to import...fairly quick and painless.
One thing to be aware of...When generating a Slate in After Effects, a new composition is created which nests both the slate and your original video/animation (as to not disrupt your originally video/animation timeline). Because of this, you'll need to create your slate in AE first, then import it into Premiere via the dynamic link method above vs. creating a new After Effects dynamic link directly in Premiere and then generating the slate inside of it.
Again, this method isn't ideal, but it is a temporary option (assuming you have After Effects of course).
