Hi @kennknowles ,
This issue seems to be a good initiation of my journey towards contribution to FOSS projects.
Can you please assign this to me?

[kennknowles]

Sure! Thanks!

Hey team! Has there been any progress here? It would be nice to not have to write an explicit PTransform to skip a a header or two!

any progress ?

[kennknowles]

Based on the progress I am going to unassign this so it is clear that someone else could pick it up.
