I've solved my problem using the 'save to disk' feature. It's not perfect but it works well enough.
Anyway, I think the optimal solution could be if we could tell Calibre that an specific device (not a model but a particular device) should work as a given model. I don't know if there is any kind of id for each reader (such a muc or similar), but if we could do that, it would be great, because we could customize the behavior for any single device, even if you own more than one of same model.
Thanks a lot.
