Tmux settings session-wide but not global

Question

I want to set style options for a session (all windows in that session), but not globally (i.e. I don't want to change settings for other sessions).

If I use

set window-status-current-style bg='#000077','fg='white'

then it only sets for the current window, not all windows in the session.

If I use

set -g window-status-current-style bg='#000077','fg='white'

then it sets for all windows in all sessions.

How do I do 'all windows in the current session only'?

• John Allsup: One workaround I've found so far: tmux list-windows | cut -f1 -d: | while read s; do tmux set -t "$s" window-status-current-style fg='#ffffff',bg='#770000' done But this is a little ugly.
