Add a label for each account

Hi,
I would like to set a rule (or a number of riles) that adds a specific label for each email account I have.
I have 6 email accounts that I currently sync, and I would like that, for each of them, when an email has been received, EM Client automatically adds the right label for each account.
How can I obtain this?
The main goal is to have, in the “All Emails” folder, the possibility to show a subset of them, simply selecting only the labels I want to read.
Thank you!
