Emporia Vue 2 3PH Panels with 19 circuits to monitor

Just flashed my Emporia Vue 2 and LOVE it! I have three 3PH breaker panels with a total of 19 circuits scattered throughout that I would like to monitor. Can I use the three 200A CT Sensors on the remaining 3 circuits I want to monitor and still get a rough idea of what my power usage is? For my 3PH devices (they are Y config) I am only measuring one leg for 220 subpanels, 220 A/C, and 220 dryer I have a CT sensor on both legs.
