In Files, can a "custom attribute" be added that generates an automatic sequential number, structured with a certain number of characters (e.g. options for X, XX, XXX, XXXX, etc)? For document management, we use "codification" structures to assign numbers to all of our documents, and part of that ideal codification involves a number. If we could have a sequential number automatically populate, rather than have to add the next number in the sequence automatically, that would be incredibly beneficial and reduce the risk of errors.
