Migration from Google Calendar to MS Bookings?

Hi,

I'm helping someone who is using Google Calendar to keep track of all his customer appointments to setup MS Bookings. Is there a way to migrate the hundreds of existing appointments (with full details) from Google Calendar to into MS Bookings? I have found the option to link a user's personal O365 Agenda to MS Bookings but this only shows up as blocked time in the Bookings agenda. 

Any thoughts?
