How many slides can we put in Storyline?

I have a client who wants a flashcard type of course for people to practice before a test. They want 500 slides. The version I found on the community uses a slide for the question and then a layer for the answer.

The project is very simple but I am concerned about having 500 slides. Are there any limits on Storyline 3's ability to use that many slides?

Thanks for the help.
