Default slow mode for threads

On a channel settings, we should be able to define the default slow mode for any new thread created in this channel. (This default value should still be updated manually by admins for a given thread)
At the moment, as an admin I have to manually enable slow mode for every new thread, or rely on a bot to do it.

Current Channel settings :
SLOW MODE
[Disabled - 5s - ... - 6h]

Proposed Channel settings : 
SLOW MODE
[Disabled - 5s - ... - 6h]
THREADS SLOW MODE
[Disabled - 5s - ... - 6h]

(Note : This functionality is already present for "Forums" channels : you can set slow mode for both the topic creation and for the responses to those topics.
In my case, "Forums" channel don't suit my needs and I need slowed down threads in regular channels)
