Slowmode Customizability: Make it affect people with the Manage Channel/Messages Permission

It'd be wonderful if there was an option to enable and disable specific roles from being included or excluded from slowmode for specific channels, rather than making it intrinsically tied to Manage Channel and Manage Messages permissions.
I'm on a server with a politics channel that uses slowmode to force users to think before they type and keep the energy of any discourse civil and, well, slow. The only problem is, there is a fair number of moderators on the server who frequent the channel, and they are excluded from the slowmode, which they all agree is pretty unfair. (Doesn't help that some of them get excited and like to paste a bunch of lines in quick succession.) But I still want them to be able to moderate said channel, deleting messages as needed. But if I give them the Manage Messages permission, they are no longer affected by slowmode.

The ability to pick and choose who gets affected by slowmode, regardless of whether they have the Manage Channel or Manage Messages permission, would be lovely.
Thanks.
