To expand slightly on what Scott said:

That's impossible because the software would have to create the same
output for given input (subject), and the UUID types commonly used
(type 4, mainly) are based on random values, i.e., they don't take a
subject as an input and consistently create the same derived value
from it. That's would be a description of a hashing alorithm.
Which is what ComputedIDs use (because there's nothing else that would
work, essentially).
