I am sorry I have no example to show you.
But I have a customer here in Italy that is dealing daily with that kind of tubing/piping spec.
They managed to do it by adding new nominal bores in Paragon (NBRWLD)
So for example the adaptor you were mentioning would have an arrive bore of DN25 (1 inch) and a leave bore of "dummy" DN21 (that means 21.3 OD)
Hope this helps
