Color columns with config from query without reducer

**Why is this needed**: Currently, when trying to color columns of a table based on the value in a different column, as far as I know, there are two ways to do so using the config from query transformation: 1) value mappings/value and value mappings/color 2) Color (and a reducer) This is nicely shown in the Demo: Grafana Features / Transforms - Config from query dashboard (https://play.grafana.org/d/Fc6gwV4nz/transforms-config-from-query?orgId=1&from=now-6h&to=now&timezone=utc) Method 1 - panel 'Value mappings from query result applied to itself' Method 2 - panel 'Custom mappings and apply to self' However, not every use case is covered by these two methods. I have two columns, one with a dynamic name (from an SQL view). One contains values, the other colors, e.g text1, green, text2, red, text3, yellow etc. I can't use value mappings, since the name of the column is dynamic (so i can't select it in the list of fields) and I can't use the 'color' option, because the color can be different in each row and the 'color' option requires a reducer like last or first. **What would you like to be added**: When using the Config from query results transformation and selecting 'Use as' - Color, in addition to the existing options like last, first, max etc. Add a new option like 'per row'. That applies the value from one field as a color to the fields specified in 'Apply to' in the same row. That way a regex can be used to specify which columns should be recolored and each row is treated separately. **Who is this feature for?** Anyone with a problem similar to the one described in the first part of this request.
