How to set UDA in Lexion in order  to  q catref ?

In design module, I want to see a UDA by q catref.
How to do in Lexicon?

First your question is not clear,Still what i understood is'You want a UDA with catref name in design'
1.You can query it by q catef
2.what to you want to achieve by this?
?

sorry,my question is not clear
I want to query it by goto catref in design module

Still not understood,what is your expectation?

For example
uda is customcode
click a flan
q var !!ce.catref.:customcode

Then you have to create UDA with UDNAME equal to customcode and ELELIST should contain SCOM.
Then all SCOMs in Paragon will get this new UDA and you can fill it there. And then query in Design like you mentioned

Now, I have a new question.
click on a flan
q var !!ce.catref.:customcodeA
but I don't want to see customcodeB on catref
click on a gask on catref
q var !!ce.catref.:customcodeB
but I don't want to see customcodeA on catref
