If you have all of those forms hosted somewhere (like on your business website, or as a Google doc) you can add a link out to those forms in the automatic email that goes out to clients when they schedule with you. Check out these steps:
Head to Settings and click on Policies
Choose Email Policies
Here, you'll be able to customize the message (and add a link out to those forms if you want to try that trick laid out above 👆). Save your changes!
