The idea of --onall/--nonall is to never write 'parallel ssh {}'.
Instead you will keep the list of servers in .profile/sshloginfile or
you will use -S to select a different file or --profile to select a
different profile.

Please test --tag (from git version beef9c1) and see if that solves your issue:

  parallel -S .. --tag --nonall run this

  parallel -S .. --tag --onall run this ::: with these args
