That addresses some of what you want…but not all of it….
you are taking about propagating style changes across multiple existing titles….
particularly with font style changes, this can get tricky…
Might want to consider doing
the text part of titles as a multi layer photoshop doc….
then using the various layers as the text portion of your titles in Ppro…
that way if you decide to change fonts…
you can multi-select layers in Photoshop….
change the font…
resave…
then it will all be updated in PPro….
