TMS: Disable auto add to buffer

Hi,

I have a client who have configured their TMS in such a way that when a transport is imported into QAS, it does NOT automatically add the transport to the buffer for PROD.

They wish to add transports to the PROD buffer manually.

Sometime in the past couple of weeks, this has stopped working.  And now when a transport is imported into QAS, it's automatically added to the buffer for PROD.

Does anyone know how to turn off that setting? I need to revert back to transports NOT being automatically added to the buffer.

Thanks
