Thank you for your reply, your suggestion only helps for future rules regarding these 2 objects only and this was not my intention.
If tomorrow I will have a different object on which I need to do the same, I will have to go through the same thing all over again, I am asking if it's possible to add a new object to all rules applied for an existing object, or if to rephrase:
How can I clone a host object into a new object along with the rules applied to it so I won't have to go through "Where used" for 20+ rules and manually add the new object.
