Assuming I understand you correctly as wanting {lo broda se broda ro da}
to have only the "EYAx" interpretation, this is in direct conflict with
the gadri BPFK section, which says
"Any term without an explicit outer quantifier is a constant, i.e. not
a quantified term. This means that it refers to one or more individuals,
and changing the order in which the constant term appears with respect
to a negation or with respect to a quantified term will not change the
meaning of the sentence.".


 

Then your assumption is false. I don't want {lo broda cu se broda ro da} to have only "EYAx B(x,Y)" interpretation. See the table at

The statement "there exists a function f(x) such that for all x,
P(x,f(x))" is logically equivalent to "for all x, there exists y such
that P(x,y)". 

There is, however, a difference between these two metalinguistic statements:

"There exists a function f(x) such that the speaker of the sentence is claiming that for all x, P(x, f(x))" and  "the speaker of the sentence is claiming that there exists a function f(x) such that for all x, P(x, f(x)".

CLL-lo uses the second interpretation when interpreting such sentences.
