Can you save custom color configurations?

I figured out how to do custom colors on the Light Strip Pro, but once you have it, can you safe it so you can make others? If I switch to one solid color, the custom config disappears.

Also, is there a way to show a pattern on multiple strips? I have only found how to do them individually. I can control them as a group (on, off, timer) but I can’t apply a color selection to the group.
