Add new platform after release date?

Hello, I’m Henri, I’m new on Imusician. I just created my first release but unfortunately I didn’t notice that I could choose more than one platform. I only put one instead of 4. Is it possible to add platforms to my release after the release date?
Thank you very much for your answers and your help.
