If you're asking if there's a way to assign the same production to multiple worlds with one button, there is nothing like that in the current game that I have seen.
If you have 97 core worlds, even in a larger universe, you might want to rethink that strategy unless you really want to have 97 shipyards, since colonies can't have them. I think most posts I have seen here agree that having fewer core planets with multiple feeder colonies actually builds stronger core planets faster. That was actually the Dev's intention with the colony mechanic. I know I had to retrain my brain since it was programmed to making every planet a core world as soon as I could get a good leader to make into a Governor. Just food for thought.
