Welcome to the community, @Alyson_Burks!
Unfortunately, when you sync to an external calendar, Airtable only sends the primary field name of the event (along with the start time & end time). Airtable is very underpowered in these regards. I would highly recommend emailing support@airtable.com to ask them to improve this feature.
For anything more complex than that, you would need to custom-build your own syncing workflow. You could do this by writing your own custom JavaScripts, or you could do it in a no-code/low-code way with an external automation platform like Integromat.
p.s. I am a professional Airtable consultant and a Registered Integromat Partner, and the Integromat link contains my personal referral code. If you have a budget for your project and you’d like to hire an expert consultant to help you with this sort of an automation, please feel free to contact me through my website at ScottWorld.com.
