Translation of beeinflussbar

I work as an actor in the theater. I have studied English for seven years, French and Spanish for two years. Well, my level of Spanish is too low to have a good conversation, but I understand it.
I've also looked at the interface, and found it a good idea to include the colloquial option. Would it be very complicated to add the most important regional check box, like Spain, South America or Central America?
These may be linguistic and cultural differences. There are indeed various regions throughout Spain and the word choice is not always the same. It is sometimes hard to understand people from other cities.
