Can coppermine have a M - M relation between categories and albums?

[cbriarnold]

I want to be able to allow albums to be in more than one category.

For Example:

B-DayCategory
     Son1B-DayAlbum
     Son2B-DayAlbum
Son1Category
     Son1B-DayAlbum
Son2Category
     Son2B-DayAlbum

In the current stable release cpg1.3.5: not possible
In the unsupported beta version cpg1.4.x: possible using the album keyword feature
