Rendtions not updated with new version

Hi, we want to update the renditions of an asset, but when we upload a new version only the original and the preview are updated automatically. Is there a way to update the renditions without changing the url?

Sorry for my english,

Thanks.

Renditions are copies of the original file. In order to replace a rendition you need to remove it and re-create it.

Yes, but if re-create the rendition, we got a new URL for it, and is very important for us to maintain the same URL. There is not other way to do that?

Thanks.

There is no way currently to replace renditions.
