Listings imported from Rent Manager into ShowMojo can automatically be set to Not Allow Showings on a Listing Before a Specific Date. This setting can be enabled on the Listing Import Settings page in the Rent Manager Import section.
This feature relies on the Don't Show Before UDF in Rent Manager. When the setting is enabled, ShowMojo will continuously sync this date (or the removal of the date) for each listing from Rent Manager to ShowMojo. The available showtimes on each listing will be adjusted based on that don't-show-before date.
