Awesome, look forward to the fix.
As is your right to do so as the developer. That said, in this particular case, it's fairly binary. You can either create a new topic or link an existing one - I can't see any other option that anyone would need\want. Both use cases are valid and as far as enhancements go, this would be one that would please a lot of your customers.
I sense a disturbance in the force with both user base and developer. I really hope you will reconsider.
