Toggle checkbox in the usetransport

Is there any way we can toggle "use transport" check box mark/unmark in the selected objects of the model?

You can toggle the Use Transport checkbox on one object and then copy paste this variable to the selected objects. Here is an example:

1. Toggle Use Transport on Processor1
2. Open the Edit Selected Objects window (in the View menu)
3. Select Processors 2, 3 and 4 with Shift or Ctrl
4. Select Processor1 (left click)
5. In the picklist next to the Variable button, select usetransport (it's the last option)
6. Click on the Variable button. The variable usetransport will be copied from the highlighted Processor1 in yellow to the selected objects in red.

Thanks clair for explaining.I know of copying variables but never thought of using for checkbox.
