Can Dispatch be used to run the Set Revision command found under the Explorer Modify menu?

Ideally, I'd like to create a dispatch to prompt the user for a revision letter and then have dispatch run the Set Revision command to assign the corresponding revision scheme value based on user input value.  This would allow batch processing of files to set the revision scheme.  Currently, a user has to manually select a revision for each item shown in the Set Revision dialog box.  There is now way to select all files and set them to a revision.
