Custom entities with regex pattern #85
Description
I'm ingesting some data from Slack. Slack formats its messages with some custom templates. For example:
Custom emojis are surrounded in colons :slightly_smiling_face: and :green_checkmark:.
At-mentions are re-encoded similar to this: <@U024BE7LH> <#C024BE7LR>.
More examples and docs here: https://api.slack.com/reference/surfaces/formatting#retrieving-messages
How can I have wink tag these known regular elements? It seems like learnCustomEntities is the correct path but it needs to take a regex pattern.
