How to change the file path of a photo / video OR how to copy effects?

I have 2 pictures in my video. Both photos are linked to the same file but they should be linked to different ones.

I already set up the effects (certain movement) for the pictures, so Id like to simply change the path for the picture so that it loads picture_2 instead of picture_1.

Rightclick -> properties -> Path file shows picture_1 now Id like to rightclick the path file and choose picture_2. Is there any such option?

How I tried to resolve it (obv. failed):

At first I tried to rename the file and as it says: "Can't find picture_1, where is it?" I select picture_2. But then both paths are changed to picture_2. So that doesn't work.

Thanks in advance
