For example, if there is more than one symbol to represent a 74HCT00, a refdes renumbering program could identify that all the instances belong to the same part, and assign slots properly. A natural key could be a company part number, but many don’t create company part numbers, so an artificial key may be better in this case.

There is no panacea.

But, for the case you just described:

- provide a tool to reset the surrogate keys on a page
- provide a tool to make the file copy and automatically resets the surrogate keys
- encode the filename and surrogate key to create the unique ID

These features won’t work in all cases, but they are much better than doing everything manually.
