Macro to seperate file name

Hi all,

I have many  old projects and need them to populate with custom properties.

If possible i need something like this:

SW-FILE NUMBER_SW FILE NAME

And i want to display "SW-FILE NUMBER" in one custom property row and "SW FILE NAME" in second row.

I have real many parts and i need to change all sheet formats and about 10 custom properies to populate manual and tray to make it faster then by now...

""_""shud be the breaker line between two options.
