Thierry-lc on "limit user acces to one album"

hi,
congratualation for this beautiful software! I tested all galleries since one week, and this on yesterday and found all the best here.
just except one point: how to limit user access rights to one album only ?

Is there any simple way to set users rights like:
user 1 to album 1
user n to album n

and maybe user x to albums a,b, ..., x

thank you for the help.
