CSV Reader Transformation -- Renaming columns

Hi,
Small quality of life suggestion… The CSV Reader (and presumably File Reader, though I haven’t tested it) should check whether columns are checked/included before validating a new user-given column name. In the screenshot below, I have unchecked column “cluster” from being read, and I tried to rename column “cluster-imputed” to “cluster”, however the node says I cannot do this. Now I will have to add two additional nodes: column filter, column rename…
