How to filter out curtain wall out of wall category?

Hi, I want to select only nontransparent elements for daylight analysis, however selecting walls also selects curtain walls. Is there a way around that?

Not knowing the particular types I came up with this solution.

It Queries Elements by Category then provides a set of all Types found, which you can then select which types you don’t want, then does another query combining the category filter and inverted type filter.

This might do the job I believe.
