Allow for subsequent mentions after the first in a server or DM to be muted

I have a habit of sending several messages to convey a single point. This tends to be somewhat annoying, as while I'm DMing someone, they'll give six or seven alert pings for a thought that could have easily gone in a single message. I know I'm not the only one who types like this, so I propose the following: An option called "Mute multiple mentions" or something along those lines. It can be toggled for specific servers/DMs (and maybe channels?), and when toggled on, it leaves a single ping unaffected. However, if you are @Mentioned or messaged any number of times after the first, it does not make an alert sound or pop up in the overlay. When the mentions are marked as read, it resets, meaning the next ping will alert you as normal. This results in my strings of messages only giving the recipient a single alert noise, instead of bombarding them with fragments of messages. It also helps deal with @ spam, giving the recipient/victim a single ping, even if they are sent dozens.
