<h4 dir="auto">How to reproduce the bug</h4>
<ol dir="auto">
<li>Create a Table Viz</li>
<li>Add the same column in Percentage Metric &amp; Sort By fields</li>
</ol>
<h3 dir="auto">Environment</h3>
<ul dir="auto">
<li>superset version: 0.37.2</li>
</ul>
<h3 dir="auto">Additional context</h3>
<p dir="auto">Add any other context about the problem here.</p>
<p dir="auto">We are in a situation where we want to split the exact same dashboard with a different dimension depending on what we're testing.<br>
Right now the only solution we've found is to duplicate every slice in the dashboard, change the dimension we use to split data for every single slice, and recreate a new dashboard with all these new slices.<br>
It is very time consuming, and it is quite hard to keep all these dashboard up-to-date as we add metrics in a slice and so on.</p>
<p dir="auto">It would really save us a lot of time if we could have a single dashboard and choose which dimension(s) we split the data on at the dashboard level.<br>
A way to acheive this would be to add an (optional) "split" field in the filter slice, in which we could specify which dimensions we want to split data on for all the slices in the dashboard</p>
