No, sorry. There are not plans to edit multiple FP objects simultaneously.
It would be very complex to implement this feature, because some parameters change depending of the state of other parameters.
Also, Max rollups don't allow to edit multiple objects. We should replicate all rollups in our custom dialogs.
Anyway, there is a specific button to copy camera properties from one FP object to all the others. You can find above the Camera pick button (labeled as "Copy").
