Is there a way to let User Sync create new users on slave site using the default role

I use User Sync to add new user to all sites I have so that my client could use the same username and password on all of them.
But each site is defined with a different default user role as required by the theme on each one.
Is there a way to configure User Sync to add new user accounts on each site and set the role, based on the default user role defined on the site ?
