You could use a "Data Page" to change the text in the paused super.. You need to create a new group in the sequencer that will hold a page with the new text that you want to replace in the super. Click on the group, and change it's Playout Mode to "Data Pages". Then drag another copy of your Super template into the data page group. You can edit the text for that item to be the new text that you want to replace in the original super (which should NOT be in the Data Pages group). When you put the original super page to air and it is paused, you can now edit the copy in the data pages group and double click it. This should replace the text in the on-air copy of the super. The data page should say "Applied". You can then resume the original page when you are ready to play it out.. When the original page goes off-air the data page will be taken off air as well.
You can have multiple copies of the scene in the data pages group with different "preset" values that you might want to change the super too.. You can even put the data page on-air before the original super page, in which case it will get applied as soon as the super goes on air..
Hope this makes sense..
