No. That is not possible.
There a feature that can help on that, but it is very basic. I mean saving and loading patterns.
I.e. if you select something in a pattern, and go to file, save as, there is the option to save a pattern, instead of saving a song (see the filter dropdown).
Once saved, open the other song, open the pattern, and then position the cursor where you want and paste.
As i say, it is pretty basic and probably could be improved someday, but right now that's the only way to do what you ask.
