Show existing groups when making new group with the same members

I feel like a lot of people end up having a lot of group DMs with the same people in it.

That's why I think it would be useful if, whenever making a new group, it shows a list of groups that already have at least all selected people in it, with a button like "jump to existing group DM instead" next to it. This way people will be less likely to make new groups, and you wouldn't have to go through the monthly struggle to leave all abandoned group DMs.
