If you are meaning, can you display things on both panels that are also displayed on the other panel, then yes. Like you could have a turnout on the LE pane and a toggle switch on the CPE pane for the exact same layout turnout. Same for sensors and other objects.

For example, I used a LE panel to describe a layout and generate the signal logic. I then built a CPE panel to be the CTC control for that layout. They work together very well.

Let me know if you have more questions about multiple panels. Just remember, they all are contained in a single file. That’s why sometimes when I’m explaining I use the word pane instead of panel. A single ‘panel files’ can contains many window panes of different tools, views, LE or CPE, etc…
