Hi Juan, thanks for asking, you can add static export fields via our snippets section:

e.g. Adding static Order fields to the Orders export type sounds like it will fit your needs. The work I’m doing on Export Templates for the 2.1.3 Plugin update will help you alot here too so you can set different field selections for different Scheduled Exports 🙂
