Appointments+ 2way sync

Loving the plug-in so far. Couple of questions.

The 2 way sync, works great. However is it possible to have the Import and Update Events from GCal button work automatically. For example if I make my own appointment in my gcal, this slot will still be available for someone to book through the plug-in until I have hit this button. It would be great if this happened automatically.

Is it possible for the booking calendar for the end user to just display slots starting from when they are available. For example if I am fully booked 2 months in advance, the first slot shown on the screen should be the first free one in 2 months time.
