Student licens for one program together with other licens

I have the "light version" of Adobe Suite through my work place (psd, indd, ai, bridge). Now I need AfterEffects wich is not covered in my work licens. How can I add a licens for After Effects without having to pay for all the programs I already have? I am also a student, can i have a student licens for a single program and use it together with my work licens?
