In the New Reservation dialog, it will show the appropriate sites if you have "Show Available" and "Use Preferences" checked, and select the site type and other preferences you want (50A, phone, etc.). So then all you have to do is double-click in one of those sites.
You can have it always select Show Available and Use Preferences by default, under Maintenance / Program Options / Reservations.
If you don't have things like Phone and 50A as check boxes under Use Preferences, see:
