[web2py] appadmin when routing domains

[Plumo]

I am using routers for multiple domains like this:

routers = dict(
  BASE  = dict(
      domains = {
          'domain1' : 'init',
          'domain2' : 'admin',
      },
   ),
)

Problem is when accessing domain1/appadmin it redirects me to domain1/admin 
to login, which does not exist. That app is accessed by domain2. 
If I login to admin at domain2/admin and then try domain1/appadmin, I am 
redirected again to domain1/admin.

Is there a way to use appadmin when routing domains?
