Changing what btrfs subvol KDE Dolphin uses for disks in Devices list?

I have a computer with three disks: an HDD, a SATA SSD and a NVMe SSD; all three using btrfs.

The whole system is installed on the NVMe SSD, except for /home and the XDG user directories.
The other two disks have the following subvolumes and mount points:

SSD
@ → media/ssd
@home → /home

HDD
@ → media/hdd
home/<name>/{@Documents,@Downloads,...} → /home/<name>/{Documents,Downloads,...} (apart from Desktop which is kept on the SATA SSD)

The idea is to have the whole home data outside of the system disk and spread over the other two, and then be able to use the two mount points in /media for miscellaneous data storage.

Dolphin, however, uses the "wrong" mount points in the Devices list for both disk entries, with no obvious options to change them: I want to have them use the two mount points /media; but instead for the SSD, it points to /home; and for the HDD, it points to /home/<name>/Documents.

What I've tried so far, and doesn't work, is:

• Using x-gvfs-hide and x-gvfs-show in fstab (also tried with comment=x-gvfs-hide)

• Removing all mount points except for the two in /media from fstab and using systemd mount for the rest (https://bbs.archlinux.org/viewtopic.php?id=178734, I know this was on another file manager but it was worth a shot)

I've also seen people suggesting udev rules, but I'm not sure if those would work for subvolumes.

I know that I could hide the entries from the list and make entries in Places, but I'd really like to keep the separate entries for the disks in the appropriate section (as you can't move custom entries to Devices).
