Automod blocking discord links with exception

I know automod supports custom words blocking based on Regex. In order to block spam servers invites, I set the rule as discord\.(?:gg|com)\w+ it blocks ALL links from discord.gg and discord.com. But there are a few server which I would like to allow these links, also links to channels inside this very server. The only way I know is to look for all invitation links of these servers and add them as exception, but this is a very ugly and ineffective approach.

Considering we are talking about Discord servers links, I think automod should have a built in invites sharing management.
