Yes, you can choose what roles to be synced and what not.
There are several types of roles in a WordPress site. Some are the default and some roles are custom. Like, WooCommerce has two roles – customer role and shop manager role. “Share Logins Pro” shows every type of role in the drop-down menu.
Admin can choose one or multiple roles to be synced from one site to another.
From the Share Logins Pro first, go to the configuration then select Migrate sites, in the user roles section you will see all the available options.
