Target custom Lync Presence by user

[straytoasters]

I am wanting to set a custom Lync 2010 presence targeted at the logged in user. For instance Supervisors would get one set of custom presence's, and non-managers would get another set. I know the custom presences are limited to four, but the idea is there would still be two custom presence files, but the one actually used would depend on who logged in to the machine. I guess the idea would be to target a user groups vs actual users but in any case to not target the machine group(s) as is being done now (certain machine's now get certain custom presences, regardless of who is logged in but supervisors could be on machines not usually supervisory specific).

If more then four presences can be used, that would be fine too, and good to know.
