I have had a feature request or two from people whom have wanted to add individual domains to my [regexp list](https://github.com/mmotti/pihole-regex), but I have been trying to keep it as broad as possbile to avoid enforcing my personalised wildcard blocking onto everyone.

But if you create this list and know which entries are regex (using a flag or so) you could adapt your injection: Split the file in regex and non-regex. The non-regex file is imported as an **adlist** at once (run gravity afterwards). Only the regex file has to be injected line by line into the database.
