automatically delete voicemail after forwarding to email

We are converting to Zoom Phone. Our old provider allowed us to set a user's phone so that incoming voicemails are forwarded as email attachments, and then automatically deleted (or not stored in the first place). We basically had three options: 1) store voicemail, 2) email voicemail as attachment, or 3) both.  It appears that Zoom supports options 1 and 3, but not 2. Did I miss something?  Many of our users, having dealt with a voicemail that they received in email, don't want to bother with deleting the original voicemail as well.

Thanks!
