Option to delete ALL voicemails. Or Select All and delete

Shifting an extension to my new front desk person, and previous user has 350 plus voicemails in the system. It takes about 5 to 6 seconds to delete a single voicemail from the list. I do not have all day to do this. This seems like a pretty obvious option to me. Either Delete All voicemails button or Select All voicemails for Marked, Download or Delete just as in any email client.

Absolutely staggering that they don’t have this feature. My wife wants me to dump Ooma.
