Integration of Google calendar and booking system Bokun

Hello! We are beginning to use a booking system for sightseeing tours called Bokun. Bokun does not have a way to see all available tours (products) in one place. However, I need a way to manage all the availability in one place, so I can accurately assign guides (resources) to products. Currently resources are managed on Google calendar. In other words, I would like a way to see all our product availability in one place (for example on Google calendar). I also need to be able to edit that availability via that place (ie via Google calendar). For example, if I remove a Product A event from Google Calendar on September 1, I would like that product to also be removed from availability on Bokun. Alternatively if I add Product B availability onto Google Calendar on October 1, I would like that product to also be added to availability on Bokun. Some products have time restrictions ie they are available at 10am OR 2pm. Others have set times ie they are ONLY available at 10am.
