edit or replace multiple essential graphics titles in one go

HI,

So i have a project for an awards show, each award is a separate sequences, all put together in a master sequence. so that common elements could be added.
one of which was an essential graphics title HashTag, that appears in various points. now the hashtag has changed, but I cant find a way to sellect all those titles and change oe line of text. am I missing something?

my work around solution was to nest the first title and use that nest where neccesary, just in-case it changes again! is that the actual workable solution?

thanks in advance
