In the video tutorial "Multi Company" the structure shows an independent seperate database for each company with access from the mother company to the subsidiaries (at min 1:06 of the video tutorial).

Then the video describes how to add a company - thats clear but presumably the company is created in the same database than the mother company.

How can I create a subsidiary company within a seperate database and establish a link from the mother company to the subsidiary (so basically the database from the mother company needs to have a link to the database of the subsidiary company).
