Hi Qualtrics Community!

Is it possible to add coded response options to text entry questions? For example:

MOMAGE
"How old is your biological mother as of today?"
_______ years old [numeric entry, 0 - 200]
998: "Don't know"
999: "Prefer not to answer"

The 998 and 999 response above would be the checkbox for 'Don't know' and refusal respectively.

The only solution I've seen so far is to add a new variable below a text entry variable.
