If you have template-type defined in /conf/demo and expect that to be available when you create template under /conf/wknd-events, it won't happen straight forward with a property.
Per the resolution hierarchy, if you choose a common place like /conf/global and have all template-types that you like to re-use in there, then this would work.
That's the reason why I mentioned if it is within resolution hierarchy, we can re-use. With this feasibility + based on your project structure + reuse requirement + considering long run need, you can decide accordingly.
Screenshot : (To showcase that it is not just for OOTB template-types)
I have copy-pasted the empty template-type from /conf/demo to /conf/global (amended the title just for identifying)
