Yes. You'll have to open Integration Services in Mgmt Studio. Under "MSDB", create a folder(s) to store your package(s). Then, go to your package and do File --> Save Copy As. Choose your server and folder.

I think you might not be able to do this if you have your package EncryptSenstiveWithPassword though so if that is the case, you may just have to set it EncryptSenstive or DontSaveSensitve (which should be fine since its on your DB server and therefore should be limited access via security)
