Historically, the answer to that question would be no. While a future version of the application may change this, limitations within Poser do not allow saving poses that utilize FBMs, natively*. In Victoria 4 we did something a little different. By creatively re-purposing existing technology, you can now save poses that utilize Victoria 4's FBMs, directly within Poser.
*NOTE: DAZ Studio users do not have this limitation. Using the Custom option in the Save Pose Preset dialog, users can selectively record any parameters of their choosing to a Pose Preset.
