Deletion of the contacts

[LA_]

In my proto plugin I hook ME_DB_CONTACT_DELETED event and delete the contact from the Server. It works fine.
Now I would like to add an option, if it is chosen, then contact shouldn't be deleted from the server (so, it should work in the same when, like when user checked the checkbox on deletion confirmation message).
But if I add db setting CList/Hidden=1, then anyway Miranda deletes the contact (and during next synchronization my plugin adds it back).
How should I handle such case?

I've expected that if I would return in ContactDeleted function result <> 0, then Miranda wouldn't delete contact.. but it deletes it anyway...
Probably I can mark that checkbox somehow? so it will be chosen by default?

Noo, never return non 0 value out of the hook it will mess up things big time.

You cannot prevent contact from being deleted within current Miranda.

Is there any hope that it will be supported in the future?

In the meantime, can I do something that checkbox on deletion warning message will be marked for my protocol? Can I know handle of this checkbox somehow?
