Send custom field data from SFDC to Calendly

After looking through the Help Center, it doesn’t appear that there’s a way to send data from a custom field in Salesforce to a form in Calendly. For example, we schedule onboarding meetings based off of products purchased on an opportunity. We have a Calendly form that asks the user to check off the products needing to be onboarded. Ideally, that user would click the Scheduling link we have on our Opportunity records, and that product data would populate in that Product field in the Calendly form. Is such a thing possible with the out of the box SFDC<>Calendly integration?
