Mouse thum wheel to control volume

Leap 42.2
To anyone that could help me out, I am trying to my mouse thumb wheel dedicate to sound volume.
My mouse is a Logitech MX Master and it’s working fine.
Using the “Configure Desktop Panel” under Mouse Actions I am able to assign the thumb wheel (actually seen as Horizontal-Scroll) to “Switch Desktop” and it does the job.
I would like to see in the list of options “Sound Volume” , is it possible to add it to the list ?

Thanks

in plasma 5 if you just put your cursor over the tray volume icon then the mouse wheel adjusts the volume.

Thank you farcusnz for the reply.
You are wright, I can do it and both mouse wheels work in that situation. Strange as it looks there is more clicking involve, I use Win 7 as well and the Logitech configuration software allows that kind of binding the thumb wheel to sound volume control. I found this very useful when playing video full screen or music in the background while working on something else.
The “Mouse Action” control panel in Suse is a equivalent for the Logitech config software, I though it will be possible to add the volume control in the list of actions or may be a command line to create a binding.
This link, https://wiki.archlinux.org/index.php/Logitech_MX_Master, talks about mapping mouse buttons but is it the only way ? The Suse Mouse Actions panel is so close to do it.

Thanks again.
