For your custom renter agreements, two new fields are now available in the 'Insert Fields' drop-down list: booking arrival date and booking departure date.
These options are exactly what they sound like - the arrival and departure dates for whatever booking the agreement is generated for.
How is this useful?
Suppose you want your renter agreement to specify a certain condition for only the period of time when the guests will be at the property. You can use these two fields to do that - "Guest may do blah between [ArrivalDate] and [DepartureDate]".
What other fields are you dying to have?
