Can't I Load Songs except the song folder?

Hi, I just joined here, but I have a question about reloading songs.

How Can I reload songs outside of the stepmania song folder? Can't I Do That?

Stepmania looks in several places for songs to load when it starts up.
First, the Songs folder in the Stepmania folder.
Next, the Songs folder in %APPDATA%/StepMania 5.0/.
After that is the AdditionalFolders preference. The AdditionalFolders preference is a comma separated list of folder names. Each folder in the list can contain Themes, NoteSkins, Songs, and other content to load.
Last is the AdditionalSongFolders preference. This is also a comma seperated list of folder names, each of which is loaded the same way the Songs folder is.
