Changing details in the Title of a track

I need to replace the “/” in the title to be “-” instead. I have searched the forum and I can’t find a definitive answer. Any help would be appreciated.

Bizzarly, I have just found out to to this by using the Actions(Quick).

I see that you have no data in the ARTIST field but accumulated the data for ARTIST in the TITLE field.
If you want to split that up I suggest an action of the type "Guess value"
Source format: %title%
Guessing pattern: `%artist% - %title%

Please be aware, that some tracks have a hyphen as part of the actual data for TITLE, so that the - is no unique separator.
