Deduplicate Whitelist and Blacklist

We have many users who whitelist sites. This often creates duplicates. I would love a feature that upon update lists it looks at whitelist and blacklists and removed duplicates

Do you have duplicate domains in the whitelist?

yes. occasionally if we do not stay on it, we will have many. Maybe a cron job for de-duping?

As long as you manipulate the white/black lists through either the pihole CLI tool or the web interface, you won't have duplicates. How are you adding/removing from the lists?

From the admin Console.

Update:
I just updated and did a pihole -r. no more duplicates. Please disregard.
