Im looking to “chain” rop outputs so i can run multiple sims over night where when one finishes the next in line will start, similar to how you can chain mantra nodes. I know there is some post action scripts and what not but im not at all familiar with them. Can it be done through the UI or can some one point me in the right direction for the scripts?

just make them in the out context. go to out, and lay down your geometry rops there, and wire them together just like in mantra. all the dependency tools will work the same.
