Replace smart previews from iPad

I primarily use Lightroom Classic, and have a number of collections synced to the Cloud. This gives me the smart previews..

When I'm on the desktop I know I can use Lightroom (the other one) to add raw files for images already synced to the cloud. This then gives me the raw in the cloud too.

When I'm on my iPad I sometimes find myself wanting to edit images where I don't have the raw synced yet. I have access to the file though through my NAS. Trying to add a raw from the iPad to replace a smart preview results in the 'skipped duplicate files' issue.

Is there a way to disable the duplicate check on the iPad version, like in classic? Or another way to get the raw in to the cloud without using the desktop?

Thanks,
Markus
