title: Manually preselect which cluster to label on seurat dimplot?
body: <p>Hi in my metadata I have a seurat_clusters column as well as a cell_type column.
  When I plot this.</p>
  <pre><code>DimPlot(pbmc.big, reduction = &quot;umap&quot;, label = TRUE, repel = TRUE, group.by = 'cell_type')
  </code></pre>
  <p>the issue I have is for example, I have NK cells that are in multiple clusters, say clusters 1, 14, 20. I'm wondering if there is a way to specify specifically that I want to label NK cells only on cluster 14.</p>
  <p>Is this possible?</p>
  <p>thanks in advance.</p>
