Microsoft Azure Active Directory Sync should reassign company if it's currently "Rainbow"

Hi,

this is related to support Case 00531643.

I case of a mass import users which are already exist in Company "Rainbow" should be assigned to the Company which is importing the users from MS Azure AD in my opinon.

This would improve the usability in case the users registered themself before without using the provided Link to join the company. 

But it should be possbile for the Company "Rainbow" only.
