Hi,
I assume that you are using a version of JMP older than 15 because the Copy Property function was added to the Column context menu (right-click on the column header) around the release of that version.
I remember using am Add-In a few years back, but I could not find it in the JMP Add-In archives.
Let us know which version of JMP you are using.
Best,
