[Newbies] Creating a Class from composite morphs

Hello,

Is there a mechanism in squeak to select a composite morph and create a new Class? For example, you can graphically create composite morphs with the user interface by dropping various morphs into other morphs. You can save that morph to a file and read it in but there doesn’t seem to be an easy way to add it to the Class library in your image. There is a command for making a subclass but that seems to lose all of the submorphs. This seems like a feature that Morphic should have. So if it doesn’t then I am concerned that I am missing something about the proper way to develop in squeak. Can someone enlighten me?

Thanks in advance!
