iPhone setting to turn off auto-detection of phone numbers? In Safari and the Notes app on iPhone, wherever there are strings of numbers they get linked and treated as phone numbers.

I'm sure there was a setting to turn this off but I cannot find it. Where is it?

(Note: I'm not asking for how to prevent this happening on web pages as in this question, just a setting for my phone.)
It is currently not possible to disable the automatic linking for phone numbers, web addresses, and email addresses on iOS 7, and it never has been possible on previous iOS versions.
