Change footage with script or expression

[jok65307055]

Hello Adobe Com'
I would like to change a footage (almost 30 occurences on a tif image) in an AE comp using essential graphics in PremierePro.
Here are some details :
- For some reasons (almost tecnical), I can't have 30 layers in AE, so I can't switch them through a drop down list (thing I've tried)
- I've written a small jsx script which, when I run it in AE, do exactly what I want : importing a new footage and replace in in my MainComp.

So my question is quite simple : how to run that AE script when I am in PremièrePro ?
I've read that post (https://community.adobe.com/t5/after-effects-discussions/replace-footage-with-expressions/m-p/106588... but it does not really help me.

Thanks for any feedback and have a good day.

You don't and that's it. That aside your whole workflow just sounds inefficient and clunky. If the same image needs to be replaced in so many instances, simply put it in its own pre-comp and replace it once inside there. No scripts required at all.
