How to make the vehicle mass variable?

I was an occasional user of SimDriveline (Generation 1) and now I try to build a new model from the beginning (on the new version (Generation 2) by understanding all the components and relations in between.
My question is about modeling a working machine (handling equipment) and here the container weight is also included in our driving cycles. So, the vehicle mass is not constant as in the "vehicle body" block. I might add a "mass" to the translational mechanical port of the vehicle body (H) but I couldn't figure out to make it conditional (as the var_load=1, then add the load mass). One way can be engaging the mass by using a friction clutch, but then it should be interpreted as inertia.
I tried to explain in a specific case, but the case can be extended to different applications. Are there any other ideas regarding my question. Thanks in advance.

The mass of the vehicle can be made adjustable - see the documentation
The block has an option to include an externally-defined mass and an externally-defined inertia. The mass, inertia, and center of gravity of the vehicle body can vary over the course of simulation in response to system changes.

How I can define the input of the new CG? The guide say that the input must be a 2-element vector but I don't understand how i can model a 2-element vector in Simulink. I also don't understand with what criterion to define the two values of the position vector to be given as input to the CG port.

You can define it in workspace then use it in simulink with a constant block.
