Correct. The ability to edit multiple objects at once came with a much more recent version of LabVIEW.
If you have a lot of editing to do, you can create an array of references of all the objects you want to act on. Use a For Loop surrounding a property node for the items you want to change with the array of references feeding into that loop with auto-indexing turned on.
Run your code so that the properties get updated. When you're done, delete the extra code and save the VI so the updated controls get saved. Basically let LabVIEW programmatically modify the controls for you.
