Prefix Phone Post filenames with poster's username

Title
Prefix Phone Post filenames with poster's username

Short, concise description of the idea
For the benefit of those who have to download .ogg Phone Posts before listening to them, prefix the file's name with the relevant username.

Full description of the idea
I recently downloaded and listened to a Phone Post, before realising that I hadn't cleared out my Downloads folder in some time. When I went to delete the .ogg file, I found maybe half a dozen unidentifiable phone posts with filenames such as "2279.ogg".

While I knew there was one phone post made by a particular user that I wanted to keep, I couldn't figure out which one it was just by looking at the filenames. It would have been much easier to identify, for example, if the file had been called "exampleusername-2279.ogg".
An ordered list of benefits

• Easier to identify and sort saved Phone Posts by username. Not much else to it.

• Potential to mess with the server-side Phone Post filing system?
