Hello Kathryn,
Thanks for reaching out to us with your question.
I’m afraid that is not possible out of the box. The feed and the resulting .ics file that you can download is dynamically generated on request.
It might be possible to develop a customization like that, but unfortunately we are limited in supporting customizations. If you would like to hire a developer to do this for you, then I can share with you this list of devs who are known in the community and are not affiliated with us. The might be able to help you out.

I hope this helps. Let me know if you have any other questions.
Cheers,
Andras
