Default Condition in Promotions-> Pricing Rules

Our store is now planning to take over shipments in several countries.

Previously, promotional rules did not include shipping country attribute in the conditions, as this was not mandatory. We must now distinguish between the rules applicable in all countries and the rules applicable in certain countries only.

We now want to include a default condition for the shipping country with the default as India, while creating new rules to make it clear to the user who creates rules.

How is this possible and where changes need to be made to include the shipping country as the default attribute?
