Hello!
Thank you for message!
Unfortunately, the Import\Export feature was introdused later in version 11.0

I need some time to investigate how it (setup) can be done in your case as well as describe the entire process step-by-step.
It is not strightforward and requires to work with settings file manually, but still possible.
