Page 479 of the SSI Web manual has some examples of customizing text based on which ACBC question you are on. For Must-Have questions you can do something like
[%begin unverified perl
if(QUESTIONNAME() =~ /musthave/i) {
return "Attribute Name";
}
else {
return TOOLTIP("Attribute Name","Attribute description");
}
end unverified%]
to return a tooltip on non-Must-Have questions and just the attribute name on Must-Have questions. For your Unacceptable questions change
QUESTIONNAME() =~ /musthave/i
to
QUESTIONNAME() =~ /unnaceptable/i
