I want to be able to save a modified chord diagram to my pallet, so I can use it more than once.

I understand how to add and edit a chord diagram to my score. My problem is that I cannot find a way to "save" the edit. I'm stuck re-editing the chord every time I want to place it in the score. I think there is a way to "drop and drag" chords onto the pallet - but I can't make it work. I'm working in Microsoft Edge browser.
