Send leads to another custom module

Send leads to another custom module

Hello
In our company, some of the leads we import dont work, disconnected numbers or people not interested.
We would like to be able to send this leads to a custom made module.

Right now we can only convert a lead into a contact.
Is there any way to send a lead or contact to another custom made module?

Come on, theres gotta be an option for this, this is so critical yet so easy to integrate.

Thank you for the help.
