I paid 0.99 for some 3rd party app to do that for me years ago. It still seems to work.

And I'll still need it because I doubt I'll be switching to 26 or 27 any time soon.

Edit: Pass2UWallet is the name of the app I'm using if anyone cares. I'm not getting a commission for that yadda yadda doo.

TFA is from a developer that created an app to create passes in iOS (and Android)
