As mentioned here, this feature will be introduced in a patch following the launch of Path of Exile: Delirium. This feature is not currently in-game.

" Third, I have no Alva in hideout. When i go talk to her in town i cannot invite her and cannot use atlas missions.
I did skip her during levelling and wanted to use her when mapping.

You need to complete her quests.
