Easier way for adding several contacts to a society

[skypilot]

You created a new society.
You imported 30 contacts for this society from a csv file.
You have to open each and every contact to add the society  

Sugestion :
In the import dialog, you're invited to choose the society witch your contacts will belong to after import.

Sorry if there is already a way to do that, i just did not found it.
