I am trying to use Capistrano to deploy to two different roles, using Bundler on both, however the Bundler command and flags will be different. Is it possible to set variables that are specific to a role? Either something like:

set :bundle_flags, "--deployment --quiet", :role => "web"

or:

role :web do
  set :bundler_cmd, "--deployment --quiet"
end

Neither of those two options work, of course. Is there a way to accomplish this, or something like it?
