Gasoline to Cauldrons - Is there a better way to do it?

A while ago I set up coke production with 8 cauldrons. Getting the gasoline from the loading bay to the gasoline storage was easy, just one task for a handler. But then I had to set up 8 more tasks just to get the gasoline automatically to each cauldron. Am I missing something? Is there a better way to do it? That's 1.5 additional handlers just for that. I get that you can just do it by hand since gasoline lasts quite long, but I was just wondering if there is a smarter automation.
