Mobile client and compress video BEFORE upload to nextcloud server

Hi all,
is there any possibility to compress video or pictures on a mobile Nextcloud app BEFOTE it is uploaded to the server? I want to get rid of whatsup, but wa compess video and transfer much less of data… (and it is much faster).
So some setting in Nextcloud mobile app would be a good idea.
Is there any request for this? I can’t find anything.

P.S.: I know, tha I can compress media on nextcloud server, but that’s not the case. I need to compress it before uploading.

Thanks
Tony
