Two embedded gallery in one post

I’ve a nice question for you.

Is there an easy way, to embed two galleries in the same post? I refer to the wordpress embedded gallery. Using a plugin of-course.

Is there outside a plugin other than Easy Gallery Manager that can accomplish this goals?

Must I write a new plugin?

You can create two different posts, each containing a different gallery. These can be drafts or private or whatever.

Then you can include their galleries into a different post by specifying their post IDs in the gallery shortcode.
