Ideas for sync on bad networks

Hi

I'm using the app to sync a lot of picture folders on nextcloud.
I let the app sync even when not connected to wifi.

Can we go further on options for the app, maybe a way to disable temporary the sync (when on bad/slow Edge/3G networks, or directly tell on the app to sync only on 4G networks)?

Actually if my phone is syncing on low 3G/edge, the battery drains on less than an hour... And I need to kill the app to stop it if I don't want to loose the waiting list of files to sync.

Thanks
