Placing the cvs in the folder you mentioned will not serve the purpose you are after...Regardless where you place the lookup table (in the folder you mentioned or elsewhere), when the .cvs is updated, it will need to be re-imported into the family
- Either Manually (Open/Import & Replace/Save/Close)
- Or using a Batch import utility
- Either a plugin
- OR using Dynamo (you can try Orchid package it has a node to add Lookup table)

An alternative to the method you are using would be to use type catalogs (No formulas involved)...The family would have a generic type and the user loads the required types upon Inserting the family. This way,
- you do not need to worry about pushing the csv back to the families since you only update the catalog file
- Downside: You (as an admin) will have multiple files to maintain.
Judging from the family sample you added, it seems that you you are more of an expert than the experts here 🙂
