Field of Lookup Module 2 Way Dynamic Connection

Field of Lookup Module 2 Way Dynamic Connection

I have several lookup fields in my custom Module 

And I have added fields from lookup fields to my module 



In my account module, I have a field called Quarterly Revenue Forecast

But this is only one way i-e the field value is only fetched during record creation, if I change the value of the field it doesn't update it in the Accounts 

There should be an option that should allow us to choose, if we want to change the value of the lookup Module field's value or not

Changing the value in Parent should change the value of all referenced fields 
And changing the value in reference field should change the value in Parent Modules Field
