Why not simply fill in the information you want and save the file to the desktop with a sensible name e.g. DesignerKitchensTemplate.kit
Then next time you have to do a design, simply double click this ‘template’ to open it and immediately save it as the client name. Your information will already be there.
If there are specific things you use in every drawing (a kettle, picture etc) then these can be stored in the drawing ready for just moving into place.
