Custom post type "Ad" booking

Hi,

I am really happy with this plugin – having lots of functionality.
I want to know that is it working for custom post types like “Ads” in any classified site.
For demo, you can see classified engine theme.
On that theme, Frontend member can posting multiple ads.
This member can set booking calender on his each ad. Any one user can book this items (Ads) from frontend site and ad poster(seller/member) can approve their booking request from frontend site.
