Move the LAST word of the tag to the beginning, eg:

Then, the newly configured text can be copied back to your choice of Artist, Album Artist, Composer, Sort Artist, Sort Album Artist and/or Sort Composer tag(s).
Select some tracks and launch; choose the format (here, "Move last word to front of tag" is chosen); then choose which tags get the edited text.
