How to associate Main adress (Location) and Geographic hierarchy

Summary:

Primary location is always per default "France" and it is not what we want because "France" is a value which is not operable with specific job-boards criterias

We know that we can change the value of Primary Location but we notice that a lot of our recruiters forget to change the value "France"

so we are looking for a solution to associate a value of the geographic hierarchy which fits with the location

Content (required):

Via the task "Manage Location" I cannot access to the value of our Geographic hierarchy

thanks per advance for your help, your suggestion
