Modification to assign parent role of children based on values in profile fields

[spinozarabel]

I am interested in a plugin (very similar to this one) except that enrollment is not in any course. A user's profile fields are examined. If a certain profile field is set to a value "Parent" then other profile fields are looked for to identify children of this parent. For these children under context user, the parent is assigned to these children (associative role assignment). This is possible to do manually but no automated bulk way such as CSV, etc., exists.
If you can suggest modifications and the code locations, I would be happy to try it out.
