Alter tags in tvshows lists

Hi,
if I display my tv series as preview images and switch on the tag display, Titan 3.6.78 shows the tags in the form

Big Bang Theory
S01E01

That is not very helpful. I would like to show up the episode name instead of the series name (series name is in the big fat title line anyway):

S01E01
Penny und die Physiker

Is there any way to accomplish this.
BTW.: I cannot update the skin because the newer versions need Kodi 17 which does not run on Android 4.4 devices. 🙁
