No, dpkg has no notion of automatically installed packages, that is an
apt concept.

You can obtain a list of automatically installed packages with
apt-mark(1):

$ apt-mark showauto > automatically-installed-packages

Then, on the replicated system where you presumably had used
"dpkg --set-selections" to install the same set of packages:

# apt-mark auto $(cat automatically-installed-packages)
