Default directory when adding to the Media Library

[bobhope2112]

When adding music to the Media Library, a directory selection dialog appears. I would like that dialog to:

1) Default to a specific directory that I define in the preferences.

or, if that's not possible:

2) Default to the last directory selected in that dialog.

My apologies if this is already on the wish list (I didn't see it,) or is already facilitated by Winamp's preferences.
