Flag regex as a spelling error?

[cringthis]

Is there a way to teach cspell that a custom regex (not just a word) is an error?

Behind this, I'm looking for a way to catch myself when I use two spaces after a sentence. I'm an old dog who learned to type on a typewriter and have always used two spaces after a sentence. Kids these days insist on one space, and I'm trying to evolve. I'm wondering if cspell can, for example, flag the regex "/(.|?|!) /" (yeah, there should be two spaces in there, but GitHub markdown is probably going to fight me on it) as a spelling error, so I teach myself when I've entered elderly comments. 😜
