How to define PREVIOUS_ALBUM/NEXT_ALBUM in export

This same question was posted to the developer forum but was not getting answered so I will try here.

I have been playing with html_milka_album_overview.mte but I can not figure out how
to make a html link referring to previous or next album in the album list.

Anybody know how to do this? Is this even possible? - When writing a file per directory,
does each invocation of the .mte file see all tracks that are selected or just those
belonging to the current directory?

thanks

I don't think that this is possible.
