Could we add a flag to setup to set the 'rvm autolibs' to an arbitrary setting?

Love the module - would it be possible to add a autolibs setting to the rvm_system_ruby.rb directive, so that we could flag it to use whatever level of setting 0/1/2/3/4 that we'd like either on a per-ruby-version basis or system-wide?

Thanks,
