Is there a way to use EPMAutomate to post annoncements to ARCS

Hello, we are just starting to use ARCS, and users are asking us to post an announcement in the announcements area once data from the various sources have been loaded. We obviously do not want to do this manually, is there an EPMAutomate command that would allow us to do this? I looked, but did not see anything that was obvious.

Thank you
