The AEO and Navigator's positions currently use Showcase "Fixed Camera" positions, however, we are investigating a method where we can assign these panels to "Internal" cameras instead, and that should improve the situation you are describing, as you will only be moving between two or three different "Internal" cameras then, rather than moving between "Internal" and "Showcase" cameras.
One method that may improve this for you in the short term is to open the MSFS Checklist Menu from the toolbar, and then click the 'eye' icon next to any of the items that are on the AEO or Navigator's panels. That will force the camera to the AEO or Navigator positions whilst still in the normal "internal" camera mode.
