Logout same page / custom page

Hi,

I'm using EasySocial in some sites which has the same Joomla installation.
Every time I log out, it auto redirects me to a menu, for example "redirect-menu" alias. So the URL will be like this:
- domain.com/redirect-menu if I log out in main domain
- sub.domain.com/redirect-menu if I log out in subdomain
What I need: every time I log out, it redirects me to domain.com/redirect-menu even I'm in the subdomain.
Is this possible?

Thanks,
Giang Anh
