Merging/Combining Two or more game modes in one?

Hi there ever since Halo 2 I wanted to make a game type where it has multiple and different objectives all in one game. Invasion was the closest thing to this.bBut I want it strictly for multiplayer.

For example the game would start out with two teams trying to get the bomb to the opponents base, once successful it reveals your teams flag that you must get back to your base.

That’s just a simplified example but the idea I have contains multiple objectives and some even simultaneously.

So can this be done in this version of Forge??

yes this is an important feature i am hopeful to learn more about.
