TMS use workflow and queue based import

Hi Folks,

i wanted to know if it is possible to use the Import Queue even if transportstrategy "workflow" is active.

we want to use the workflow transportstrategy but, we also need an import queue because the most transports in our  prod System are together in Releases.

Are there still importqueues if i use the workflow strategy?

is it possible to use the workflow only from dev to test system and manualy Import to prod System?

Thanks,

Tobias
