Collecting formatted data fields (i.e. Date, boolean, etc)

I'm just exploring bookings for the first time, and it looks like it may be a good fit for a project I have in mind.  I see that I can add custom fields to collect data with the booking, but they seem to be very limited, offering only a free text field or drop down box.  Is there any way to get more advanced form functionality, like date formatted fields, and check boxes or other yes/no selection?  

Also, what's the best way to get the data from those custom fields in a usable format?  I tried exporting appointments as tsv, but it doesn't seem to include the custom fields, just the built in fields.  

Thanks!
