In Odoo 9C:

An User has access to 2 companies, say Company A & Company B.

Now when User logs in, he can change the company under preferences to perform the activities for that particular company without worrying about the haywire of data-entry. which is definitely a wonderful features, as it strictly follows one-company-rule policy.

However at some times, I would like to view the records of both the company in One go, without toggling between the companies, which I found is not happening in the present system, or am I missing something.
