Hello Finale Hivemind!

Does anyone know of a shortcut/ plugin to quickly and evenly space multiple grace notes attached to each other? I've tried it with the note mover tool but it is tedious...

To demonstrate:
If | is a grace note
Then |‾|‾|‾| is the input and the result I would want would be |‾‾‾|‾‾‾|‾‾‾|

In particular: Is there a way to select a region using measure tool and apply the spacing to only that region? I am already aware of the global spacing option in Document Options. 


Thanks very much!
