-Put your scene in the sequencer like you always do (ie 5 take item, 1 animated and 4 non-animated).
-Create a new group and drag'n'drop all your scene in it except the animated one). At this step, you have the animated scene in a group and 4 in another group.
-Click on the second group header (of the non-animated scene)
-In parameters > Playout Mode, change to Data Pages.
After this, only data of your text object will be updated...
