If you carry out a mass mailing campaign in a multi-company system (with the email marketing app), you cannot limit this campaign to one group company (the one that sends and from which the mailing list originates, for example), but all companies in the multi-company group will see these campaigns. I find this very disadvantageous (in fact, it prevents us from using this otherwise beautiful app).

Are there any solutions for assigning email actions to just one company in the group? I have not found a company field in the action to make it local.
