Synch video preview files

i not like newer gui, in 2.x i can compare different ai model. now i can only select single version and i must synch manually.
is possible to keep in sinc all preview file along different model?
for example i do a previous with artemis and proteus, to compare i should find same frame, i would like to have a flag to keep in sinc all different previews in player, if i go to 2’11’’ on artemis previews when i go to see to proteus preview it should be at same frame.
anyway i would like to see back the old 4 views previews to compare animated version of different models.
