How to allow three or more asterisks in comments with eslint?

Eslint enforces the spaced-comment rule and while I'd like to keep it, I'd prefer to be able to have comments with three asterisks or more:

/*** Actions ***/

I modified the rule like this in my .eslintrc config file:

{
  ...
  "spaced-comment": ["error", "always", { "exceptions": ["*"] }]
  ...
}

But it only works for 2 asterisks.
