Images with same filename, but different image

How to solve a problem where the URL is different, but the filename is the same and the images are different for 2 products?

E.g.

Product one has image:

https://b2b.zizito.com/21331/detska-ranica-s-formata-na-kalinka-14665.jpg

And product 2 has image

https://b2b.zizito.com/21344/detska-ranica-s-formata-na-kalinka-14665.jpg

If you open the URLs you will see the images are different. The only difference in the URL is after first single backslash (21331 and 21344), but after that the filename is the same.

While importing, I can see the log checks (match by URL option) the name (or after last backslash) and reuses the first product image for the second product.

Is there a way to solve that?
