Sort by ASC when value is present

[olivere91]

Hello,

I'm trying to sort a column, by another column when it's present. The picture shows Categories, in bold, Names as unbolded text, and beneath the names not visible in the picture is a GL number for each name. This GL number is only present in names under the category SG&A.  I'm trying to sort these values by ascending them in my matrix. Any ideas?

@olivere91 , if you sort category column ascending then only below level will sort ascending . As of now, multiple sort is not available in Matrix visual
