My university cannot allow for H1 tags in the RTE as we have to hold that important ADA tag for the page titles. There may have been a config somewhere in the affected EE6 install (developers tied up with priorities) b/c the solution was to keep an h1-h3 dropdown but render as follows: h1 as h2, h3 as h4 and h4 as h6. I only have 3 options. I'd like to at least a 4th option (h4 which would then render as h5). Where in the system can i add this?
