Phoenix can pass data between liquid containers with "Cascade Sources." You can have different sized containers that help avoid large containers. Usually you have to sim the first one and start the next when the first sim is done. This goes "down the chain" so if you have a chain of 5 sims, you'll have to manually start each one. It's an issue if you want to sim overnight. I wrote a script that allows you to simulate down a chain of cascade containers automatically with one button.
Check out this post in my tools section to download the script.
