Unable to add multiple formats with the same name but in different albums

[oko235]

I have an album with a set of jpg photos. I want to add the corresponding raw with the web form.
However, the tool tells me that there are several photos with the same name. This is true for my entire photo library but not for this album only.

I note in fact that it is not necessary/possible to select the album for adding multiple formats via the web form. I think this option is missing because it is impossible to have unique photo names since I am using a camera with a name format like IMG_XXXX.JPG/CR2 (with X in 0 and 9). In fact, every 9999, the counter returns to 0 and generates a name that already exists in the photo library

Did I miss a subtlety to use the tool to meet my needs?

Do you have a workaround without having to go through each photo individually?
