Can you use Project Parameters in post task action tasks?

As the subject states. The support documentation says this:

Does this mean I could create an "Office" Parameter and use that parameter in the post task actions? See previous post on this here: 

Add office to the available Keywords | IMAGINiT Support (helprace.com)

So, a possible post task action path could be :
"\\MyServerName\[Office]\[Project]\Clarity Stuff"

It appears that way after read this:

However I don't see anything related to how to specifically call a Project Parameter in a task or post task action.
