Reusing File Description Text

As discussed in an old thread (File Descriptions, Multiple Selections, etc.), I currently utilize a context menu command to quickly assign a description to a file, namely:

SetAttr DESCRIPTION "{Rs|Enter Description}"

(Yes, I know the "{Rs|Enter Description}" argument is not really required, but it overcomes some inherent annoyances [mainly redundant confirmations]. Refer to aforementioned thread for details if interested.)

I searched the help file and the forums extensively and couldn't find these arguments documented anywhere, so what I want to know is if there is a way to have the description dialog box be automatically filled with the current (if any) description already assigned to the file. (With the above command, the dialog box comes up blank and you have to retype the entire description even if you just want to make a minor update to the description, correct a typo, etc.)

There's no simple way to do that. It could probably be done with some VBScript but I think it would be overcomplicated...

Why not just use SetAttr DESCRIPTION (which does what you want) and after you've typed/edited the description use Alt-A to trigger the OK Tor All button? From the other thread it sounds like the only problem with using the proper command was having to use the mouse to click the button but you can do it using the keyboard as well.
