This is a very helpful method for me using word wise. Thank you very much.
One problem is that I have the Bookerly fonts enlarged to 150 and 130% respectively and put both sets on Kindle, but only one of the two sets is recognized even though I entered different Family Names in the PS Names section. Is it not possible to use multiple versions of the same font at the same time?

-> I think I found the answer. Some fonts like Bookerly require the "preferred family" in the TTF name section to match the "family name" in the PS name section to create multiple edited sets.
