Add-on Thread Tagging Addon | Add the same tag to all threads in a specific section

[CabCon]

Hello xf,
I'm looking for a method or addon which allows me to add a tag to all threads in specific section.

For example:
I got these sections (amount of created thread next to):

• Red (43 threads)
• Yellow (3 threads)
• Green (23 threads)

Now I would like to have the option to say I would like to add to all threads in the Red section the Tag: Color Red


I would love to see an addon like this in the future!

Best regards,
CabCon.
