How can i use document packages

hi, i need to use an MPK file that contains  not a project package but several document packages. is possible to unify them all to make a project package and use it? or how to upload all this documents?

AFAIK the mpk file will only allow for 1 document.

The workaround could be to add the documents to 1 module and export the module, then import the module and move the documents to the required existing module(s). Not the best option, but better than importing everything one at a time maybe?
