addtriggerchannel to NI 9201 Device (session based)

Hello, i try to transit Code from the legacy interface to the session-based Interface. But it seems like there is no terminal in the NI 9201 Device to use an external (analog or digital) trigger.

With the legacy interface i used an analog trigger input with an defined "trigger value" for synchronisation.

Is there an other way that i can use a external trigger for the device with session based data aquisition?
