currently the Group Step as well as the Hide and Rename Step (and I think any other transformation step except of the formula step) are unique in the transformation pipeline.
Will it be possible in a future version to use multiple steps of the same type within one transformation pipeline?
This would be very useful, especially because you need a hide and rename or group step to separate two formula steps from each other. If you want to use a grouping after the second formula step and you used a blank group step for separating the two formula steps, it isn't possible anymore. You would need to create another table of the existing table in order to perform the grouping.
