Is it possible to package multiple Chrome extensions together?

Does Google allow you to package multiple, separate extensions together, so users can install all of them with only one click?

I haven't been able to find anything on the matter so I am thinking that it is not possible at this point.

I ask because I am in the process of creating useful context menu options, These options naturally fall under a few distinct categories and I would like to avoid the forced nesting that would occur If I were to put everything in a single extension.

If I make 3 separate extensions, then I can make all of them top-level options, thus creating a more convenient user experience. However, I would like to avoid making the users initiate 3 separate downloads if possible.
