Yes, it is possible to do this in TG using a movie template.
TG sees them all as one movie (if that is how they were released), so you have to use the movie name without the “part 2” etc. So, start with the first one naming it “the tenth kingdom”
1)Make the backdrop for the first part in semi-automatic mode and have it stop when it shows the info on the screen.
2)In the “title” section on the left hand side, add the episode info, such as “the tenth kingdom: part 1” or the tenth kingdom disc 1" etc
3)Hit the update button below, which will add the new info to the backdrop view or example you see below
4)Generate the backdrop/cover
5)Repeat process with the next episode, changing the title to “the tenth kingdom: part 2” or the tenth kingdom disc 2"
6)Repeat with all parts or episodes of the movie
i do this a lot with multi disc sets (disc 1 & disc 2) if I dont have the time or wherewithal to join the files into one larger file.
