That is a very special use case.. There is no built in ready to go feature like that.
But you should be able to create a UserDefinedCommand of MultiScript type to do that.
The hard part is to figure out what that the folder name should be. If the folder name can be generated from what the filename is.. then it is easier.
From MultiScript you can get all selected files
Go through them one by one and from file name create the Directory name you want,.
Create that folder and then move the file to that folder..
Then you assign that command to a HotKey/Button/Menu and when you select that command it will run that on all selected files.
