attribute selection operator

New Altair Community Member

Dear All
I have to make sub-datasets from the main one (I mean selecting subsets of attributes from the original dataset with more than 1000 columns or attributes). I have the name of attributes but cannot past them into the Select Attribute Subset area. Does anybody have any good suggestion to avoid selecting them one by one; doing that is really painful and tedious
Best wishes and regards.
