Millisecond Forums

Hi I want people to first be notified if they didn't answer a survey question and then be able to skip, in lines with ideas of informed consent and being able to skip questions. . However, it appears the status of /required does not update until after the whole trial (surveypage) has been submitted. Is there a workaround? 

I have tried a lot of options but the most obvious, which doesn't work is:

For instance this doesn't work

<surveypage cultural_religious>
/caption ="<%values.demographicpageinstructions%>"
/ fontstyle = ("Verdana", -14, false, true, false, false, 5, 0)
/ questions = [1=school; 2=govt; 3=religiosity]
/ itemspacing = 2%
/ showbackbutton = false
/ ontrialend = [radiobuttons.religiosity.required = false]
</surveypage>
And this works (changing it to not required at the beginning) but doesn't do what I want

<surveypage cultural_religious>
/ ontrialbegin = [radiobuttons.religiosity.required = false]
/caption ="<%values.demographicpageinstructions%>"
/ fontstyle = ("Verdana", -14, false, true, false, false, 5, 0)
/ questions = [1=school; 2=govt; 3=religiosity] 
/ itemspacing = 2%
/ showbackbutton = false
</surveypage>
