Sync word custom properties with sharepoint custom properties

I had a custom property(columm) on a sharepoint library called 'Status'. Whenever we would save a document(.doc) on a library, word woul ask if I wanted to save the .dot template file(Even though it was read only!).

We don't want to have this prompt show every time, word souldn't ask if we want to save the .dot file. So some of my teamates thought that it was because of the 'status' property.

So I made it so that now the property is on the word docs. Now I have a doc with a custom property called "Status". But I can't seem to figure out how to make sharepoint display a word custom property on a columm.

So, how do I make a library columm that has a doc property on it?
