You don't have to use wildcards. You can simply specify 23456. By default it will match part of the folder name.
Note that if you are including a folder, then make sure you also include the names of the parent folders. Eg: If you wish to include C:\Company\Project\1-23456-10 folder, then you need to also specify company and project in your include list.
So your list would be company, project, 23456
