Can I change part of a title?

I wish to append some information in the title field. Is there a way to select all tracks in a folder and add text to the title field without having to retype the title field for each track?

For example, I have the album Destroyer by Kiss. I have already entered all ten track names in title field, but now I wish add the Album title to the title field so it looks like this:

Destroyer - Detroit Rock City
Destroyer - King of the Night Time World ...

I'm sure I could just cut and past the phrase "Destroyer - " to each and ever title one at a time, but that is quite time consuming when I wish to append 811 titles with info. I'm hoping there is a way I can just select all the titles and add the part that I need without overwriting the part that has already been entered.

Have a look at this example:
