I have a model that outputs a signal via a normal outport. I would like to create an optional second outport for a normalized version of this same signal.
Currently the block has both outputs, but I would like the second outport to be "hidden" unless explicitly enabled.
So is it possible to add an outport that can be enabled and disabled by a checkbox in the properties of the model/block?

You can use a switch to select between the two different output options that you want, and there are a number of ways to activate the switch:
1) This is a favorite of mine: Define a logical variable (e.g. "UseOutputOption") in the Matlab workspace.to control the switch.

2) You can use a manual switch inside the model to activate the option:

After giving it some more thought, it may be that what you want is a variant subsystem.
