1. What exactly are you trying to achieve?
AS OUR OPERATIONAL HABIT WE USED AN INCREMENTAL FILE SAVING MODE FOR WHICH WE PERFORM SAVINGS (SAVE AS NAME) AT A TIMELY TIME, INDICATING THE SAVING DATE OR A PROGRESSIVE REVIEW NUMBER IN THE FILE NAME.

2. Why is this change necessary?
WITH REFERENCE TO THE MODE USED IN POINT 1 IF SHEET INDEX IS SET, WITH THE CHANGE OF FILE NAMES YOU WILL RECEIVE LINK OPENING ERROR (MISSING LINK)

3. How are you currently working without this change?
WE HAVE STARTED USING THE INDEX CARD LITTLE ONLY IN LAST PROJECTS.
ACTUALLY IN AN ALREADY ADVANCED PHASE OF DESIGN FOR WHICH THE FILES WERE NO LONGER REVISED BUT ONLY MODIFIED.
NOTICE THAT IN RELATION, FOR EXAMPLE IN THE DEVELOPMENT OF AN EXECUTIVE PROJECT, THERE IS THE NEED TO PRODUCE DELIVERY REFERENCE TO VARIATIONS THAT ARE PRESENT ON SITE, THEREFORE THE INDEX CARD IS OF VERY IMPORTANT IMPORTANCE FOR DESIGNING DESIGNS, DESIGNS AND MODELS REFERENCE FILES.
THE FACT THAT THE SHEET INDEX NO LONGER OFF FOR CERTAIN FILES ONCE UPDATED THE NAME OF THE FILE TO WHICH THEY POINT DETERMINES THE USELESS OF THE ABOVE APPROACH AND LOSS OF CONTROL.

4. How will your workflow improve?
YOU ARE EXPLAINED AT THE PREVIOUS POINT.
THIS OPTION ALLOWS TO OPTIMIZE THE WORKFLOW EVEN IN THE FACE OF PROJECT MODFICES MANAGED WITH STATIC BACK-UP COPIES THAT WE USE. THE NEED TO HAVE TIMED AND SUBSEQUENT COPIES OF CBACKUP IS NECESSARY TO HAVE A REDUNDANCY APPROACH TO AVOID LOSING PREVIOUS PROJECT REVITIONS AND INFORMATION YOU MAY NEED IN THE FUTURE
