💡 Create a filter to create Threads

[J]

Describe the improvement

Hi, I would like to suggest adding a filter so that the bot only creates Threads on messages that start or contain messages with X Characters.

Problems this improvement solves

That the bot creates threads on messages that do not require discussion or are of little relevance.

Alternative solutions

I'm not sure :(
