By default, Easy Passthrough passes through entries found during the current browsing session. To allow for long term passthrough, you can enable the User Passthrough option. When enabled, the last entry the currently logged in user submitted to the source form will be used instead of the most recent entry found in the browsing session.
Enabling User Passthrough is simple. When setting up Easy Passthrough, select the “Use logged in user’s last submitted entry” checkbox.
