Role types in Discord Servers

I do not believe there is a way to do this already and I'm not sure whether it sounds like a good idea. But here's what I have in mind: Let's say I have some discord server; on it I have two roles: Admin and Moderator. Now, I want my Admin role to be above the Moderator in rank. Here's the thing though, let's say someone on the server wants to ping @Moderator for some arbitrary reason that requires a moderator. Technically the Admin role should count as a moderator as well so they should be pinged too. Currently, in order to achieve this you must give all Admin users the Moderator role as well, which frankly is kind of annoying.

It would be really neat if anyone who has only an Admin role would still get pinged with @Moderator. To be more clear, it would be nice if there could be a way to follow this logic:

All Administrators are Moderators but not all Moderators are Administrators.

I can imagine, though, why some people might not like this idea. Perhaps it could be misused or it could over-complicate something that's supposed to be simple. Anyways, I would like to hear your thoughts on this if you have any.
