Welcome to Chordie, G&B ...
I spent some time trying to come up with a way to accomplish what you're asking, but wasn't successful. There are several Moderators in the group who are much more technically inclined than I am, and I expect one of them will reply to your question soon. The only thing I could come up with is to save each song on your PC as a Word doc or PDF, make the edits you want, and save them again on your PC or tablet. If Chordie has abilities beyond that, I'm not sure how to access them.
All the best ...TF
