Hello jacobrmcdaniel,
Thanks for contacting us!
Unfortunately it is not easy or possible to do either of these tasks with the current release.
If you have a moment, we’d love for you to submit your idea to our UserVoice forum. We take user ideas and contributions very seriously, and many times their ideas end up in our future releases.
Here is a link for the ‘rename the .ics file’ request http://tribe.uservoice.com/forums/195723-feature-ideas/suggestions/5358418-ability-to-change-the-ics-download-file-name
Also, there is unfortunately no way to export the whole calendar to Google via the Google Add to Calendar button. That feature currently only exists for single events.
Sorry for the non-positive answers!
Does this make sense? Let me know if I can explain anything else!
Cheers!
– Casey Driscoll
