Can I get release after promoted to Innovator cadre from support project?

Recently I cleared the Wings 1 and have some queries related to the Innovator cadre. Where does this innovator cadre helps us like in appraisals or somewhere else? I guess innovator is no where directly linked with C2 promotion. Kindly correct me if any of my thoughts were wrong. Is it true that innovator profiles can work in R&D projects?
