Custom Dropdown for Job Offer with Templates

Customer Requirement we have here is:

In Job Offer Creation Flow,  Add a Dropdown Menu which could allow us to select 'Create New Job offer' or 'Use Template X'

If one chooses 'Create New Job Offer' entire flow should work as normal

If one chooses 'Use Template X' then the entire flow should have fields auto populated with certain values which should be editable.

 

Our Approach: Create a DFF with dropdown as mentioned above and create a Business Rule based on selection to populate fields and their editable nature.

Challenge we are facing:  The DFF Dropdown is coming in the 'Additional Info' section of the Job Offer Creation Flow, which makes the adding of the Business rule invalid since all the important fields have appeared in the previous sections i.e. the Business Rule doesn't Fulfil.
