All sorts of ways, The way you describe is one way. Two plug-ins that might help with future projects.
A big plugin with all sorts of filters gimp_gmic_qt I do not know which OS you use but there is a Windows installer from http://www.gmic.eu That will adjust all the animation layers without splitting up the gif. Convert to RGB mode first.
Then for merging animations or adding overlays & back grounds: ofn-interleave-layers.zip (date 2020-04-25) Unzip, and read the documentation.
Just to give some idea of use, a quick video 3' 30'' https://youtu.be/zIsF1_jh3II
