How to organize USB devices indicator in MATE?

Question

linux

Of course, I understand that the question is stupid for a toaster , but the Google skill is not sufficiently pumped, even according to English-language resources, I probably don’t see the obvious in front of my nose, and yet:
Version MATE 1.6.0, bubunta.
The standard applet shows all connected drives.

Two of them are hard disk partitions - they are not needed, and two partitions are flash drives.
It is necessary to hide hard drives, preferably without changing their mount points (they are in / media).
I did not find a ready-made applet for this task in the repositories, gnome-applets, mate-applets (and common) are installed, do not give the desired effect.
This applet is currently in use

The accountants are trying to remove hard drives, but the applet has no settings.
