I think @zhaohui.chen5TEA7 is speaking about 2 main ideas:
1. Getting "in place" values in into families. My case CaseNo:15832033 "Acces "In Place" Window Sill Heigt In Window Families To Drive Geometry" was an exemple for that.
2. Combining text and Number parameters into a new parameter which is a common concept of programming known as concatenation. As familiy building is very near to programming this function is essential and for the moment just very partially realised in the family enviroment.
My reporting-x-y-z-point-for-families is a method how to get easily geometric "in place" information into families. Most of the parts of this concept are technically implementet in revit.
To be honest, one should reformulate a more general concept to integrate our 2 "ideas". If there is a chance to see this feature in revit 2022 I would invest the time to do so, I have allready done a part in my paper called "Time For Analysing The Model" (A short proposal for the amelioration of information analyses in a revit model in 3 points). Also a discussion with the developement Team would be helpful. Please keep me informed.
