How to forward emails which I receive in an email alias

How to forward emails which I receive in an email alias

Dear All,
 
I think that there is no solution until now in my question but let me try it.
If a I have an mail account public@something.com and an email alias inside of this e.g. public-theo@something.com.

Is there any way to forward the emails which i receive only to the alias (public-theo@something.com) in another zoho mail account? Because until now as I know we can forward the emails from the main email + aliases.

Or if there is any patent which i can do from my admin's panel (from the Email Policy) maybe?
