Hi guys, i am trying to rename a new created entry/document by checking or comparing the previous/old document's name in a particular folder.Example:

1.Folder A in the LF repository.

2.new document created will route into Folder A, then workflow check the Folder A, if nothing then save the new document as "invoice-1".

3.If check there is document inside already, track the "1" with the previous entry name, and increase it by 1 ,it should become "invoice-2" .or if the previous one "invoice-3" then the new document name would be "invoice-4".

can it be done with the workflow designer?

thanks and appreciate.
