we have older drawings that were never properly setup with layers, drafting standards etc. I have now created new templates with these all set. Is there a way to re insert the new template into an older drawing with all the layers etc. I am not expecting items on the drawing to automatically move onto the appropriate layers, but at least the layers would be there instead of typing them in, every time an older drawing is updated. We are using 2016
