title: How to ignore some filters but not all at Quicksight
body: <p>I need to calculate a fraction where the numerator is filterable by dimensions A, B and C but the denominator is only filterable by A and C needs to be pre_agg</p>
  <p>Today I'm at this</p>
  <pre><code>sum(numerator) / min(sumover (denominator, [C], pre_agg))
  </code></pre>
  <p>If the restriction was for all filters I could use pre_filter but it is not the case.
  And if I add B at pre_agg level, it breaks the number.</p>
  <p>Thx for the help</p>
