Try this:
In the main Sentinel window (not an "edit" window)
On the left side pane, click on the top line of your Favorites list, which is it's name.
In the right side window, you'll see all your various systems' names/
If the ones you wish to copy are all in one group (consecutively listed), then hold down the <Shift> key and click on the first and last one to select your group. They should be highlighted now.
With then highlighted, position your mouse over any one of the highlighted systems.
<Right> click
From the pop-up menu, choose "Append Favorites List". (Instead of the right-click/append, you could also use the keyboard shortcut of just the Insert key.)
Choosing append will bring up a pop-up window with a list of your current Favorites lists. You can also use the "New Favorites List" button at the bottom of that dialog box to start a new list, and you'll be asked to give it a name at this point before proceeding.
If the systems you want to copy (append) are not consecutively listed, you could hold down the Control key, and click to select those you want, picking and choosing as desired. Or, use "<CTRL>+<A>, the Select All command, to choose all of them, then hold down the Control key and deselect those you don't want to copy to another Favorites list.
Is this what you had in mind?
