Assign id to metacell object about metacell

[amissarova]

I believe I found it: scdb_add_mat would do the job for assigning metacell objects with id.
Still wondering about the ways tor un the package functionalities on metacell files directly - is it possible?

Most functions that use an id instead of an object, internally call the object to memory (if not in memory) and than work on it. You can usually (but not always) call the inner functions with the object if you need. We understand the use case, but not sure we will add proper support for this general functionality in the near future. If you have a specific use case in mind, let us know and we'll take a look.
