In order for you to add a break/termination option for a lease, the lease must be time limited.
To add a break/termination option for a lease:
Open a lease. For more information on how to do so, see section 4.6. or 6.1.
Go to the lease card (see image below).
Click the tab called "Dates" (see image below). Within the tab called "Dates" you will, among other things, find a button called "New Break/Termination option". Note that you will have to scroll the lease card to find the button called "New Break/Termination option".
Click "New Break/Termination option" (see the first image below). When you do so, a break/termination option will be added to the lease you are working with (see the second image below). Use the break/termination option's fields to set information for it.
