Not sure if you are still looking for a solution. One possible way could be to create a bookmark on the selection you would like to retrieve again.
(Alternative - CreateDocBookMark )
and then retrieve that state later again using:
(Alternative - Use the Bookmark object in the front-end -i.e. if it is for auditing purposes, create a variable using Dim with the current date - concatenate it to your chosen name - and use that as the name for your bookmark)
Hop this helps!
