Can I merge an album?

[Adriabs]

In my gallery, I have the category "Tours", and in this category I have the sub-category "The Circus Starring: Britney Spears Tour", and in this folder I have several albums with the pictures of the shows.
But now I created, inside this folder, the categories "Leg 1", "Leg 2", Leg 3", "and Leg 4". Can I merge all the concert albums in the category "Leg 1"?

Here you are the link of the album, inside the sub-category "The Circus Starring: Britney Spears Tour", where you'll find the albums with the pictures of the show and the categories of the four legs: http://britneyrocks.com/album/index.php?cat=31&lang=english

Thank you.

Update first, you're running cpg1.4.18, while the most recent stable release currently is cpg1.4.25

After that, use the edit files dialog to move files from one album to the other.
