[TYPO3] Sticky bit for page permissions

[Xavier Perseguers]

Hello,

Is there a way to set a kind of "sticky bit" as Unix has for the page 
tree in TYPO3? I created a multiple domain tree with groups associated 
to each domain (write allowed) and one editor for each domain which is 
the owner of pages. A few editors have multiple domain access but I 
would like to enforce the original group.

If I have a "super user" members of groups A and B (each of this being a 
domain), I do not know how to enforce that pages saved in domain B-tree 
get this "B" gid, they are created with owner being my super user, OK, 
and with domain A which is the first domain listed for my super user.
