"Convert" VST Instruments to Instrument Track?

When I found out about Instrument Tracks a while back, I made that switch with no question; very much easier to maintain in my opinion. But, in my older projects that I’ve now started to pick up on, I’m still using VST Instruments.
So, I’m wondering of there’s an option to “convert” a VST instrument into a VST Instrument Track?



Unfortunately it’s not possible to make this kind of conversion.
