Upload conflicts solve via hash?


I use the Android-, Linux-, Win-, Mac-, iOS- Client. How would it be to check upload conflickts via hash. if they are the same on client and server, stop trying to upload. The file is always there.
It’s because I’ve loaded the files from camera by cable to my Notebook ,because this time there are too many for SnapBridge and now the phone tries to upload Files, that are always on the Server. A hash can check, that it is the same file and stop trying uploading. That would be a nice feature.

Best regards.
