Music on Hold: how do I to do a shuffle (not the dance ;-) )?

I feel an upcoming feature request for a GUI to configurate MoH… ? 

Is there a hands on manual how to create a MoH category and assign it ti the trunks?

I was confused about the working of adding MoH (Music on Hold)  music to Vital PBX.

When you first go to Settings > Music on Hold, fill in the name, select a sound file and  click on [Save], you are actually creating a MoH list with one soundfile!
By selecting more sound files afterwards, you are adding more sound files to created list.

Within the list you can select the sort type of: shuffle or linear.
Choosing shuffle will randomly?? pick a sound file when you use this MoH within VitalPBX.
Using linear will play the sound files in the list’s order (1,2,3,…) every time when used within VitalPBX.

For me (and perhaps other VitalPBX users) changing the the screen a little might make the creating of the MoH sound list more clear (see attachment)

The proposed changes are indicated by the red arrows in the screenshot (add-button) and [save] button instead of the [update] button.
