Multiple Columns / Rows Supported in Policy Selection

[kjam]

Is your feature request related to a problem? Please describe.
When you want to apply the same transformation across multiple columns, you have to copy and paste a bunch of code. Ideally, there would be a way to say you would like to apply the same transformation across many columns.

Describe the solution you'd like
An update to the YAML policy implementation file to make it easier to apply transformations to more than one row or column.

Describe alternatives you've considered
The current system allows you to copy and paste - however, this could end up making the YAML file quite long when we are dealing with MANY columns and it feels like repeated work.
