BATCH EDITING in Adobe Express (or acrobat)

I really appreciate the new converstion tool from acrobat to express and being able to edit and change a PDF, however I wish we could batch edit things like text/fonts, headers and footers, images, across a whole document that's 20+ pages long. I know canva has a button that lets you change all font type to another, but canva doesn't conver the document as good as express does, so I would love to have these tools within express. Plus other batch editings!
