Call duration be visible directly within the caller list, rather than requiring them to open each voicemail individually to see how long it is.

Receive a high volume of spam calls/voicemails, many of which are very short (e.g., 4 seconds). Currently, we must click into each voicemail to check its length before deciding whether it's spam. Displaying duration directly in the list would let us quickly identify and skip/block short spam messages without opening each one.
