Issue with Sapera Lt Add on for Dalsa Cameras, not seen with Genicam cameras

Hello, I have a question regarding Image Acquisiton with Sapera Lt add on for Dalsa Camera & Frame grabber.

Whilst Im able to create a video object, It seems capable to change parameters of the frame grabber only thru a config file (that has previously been saved using the Dalsa CamExpert software) being passed to the videoinput

ConfigFile='C:\Program Files\Teledyne DALSA\Sapera\CamFiles\User\Dalsa Mono12_50ms.ccf';   
vid = videoinput('dalsa', 1,ConfigFile)

1: So wanting to make changes to the frame grabber i.e. 8 bit or 12 bit has to be done by recreating the video object with a different config file - this is very clunky

2: It appears, that changing parameters on the camera itself (which is also gentl compliant) such as exposure time is not possible

So does this mean there is no way within Matlab to change the exposure time on Cameras attached to frame grabbers within Matlab?

I've aslo seen this ability to change parameters hasn't really been answered previously
