unlock France in Peninsular campaign?

How do I unlock France without beating the campaign as one of the other factions? Is there a script I can easily modify?

My Great Britain campaign has stagnated horribly since the French are able to spam new stacks out of Toulouse so I will never capture it. And I have no wish to play as Spain.

you take the seaports with Britain and field multiple armies. Give provinces to spain so they share in the burden

My memory seems to be less dependable as age comes by, but I am most certain that in my Peninsular Campaign, I did not need to unlock France. They could be played right off the bat.

Yes, I concur with MortenJessen France was the first faction I played after I downloaded the Peninsula Campaign. There was no need to unlock anything.
