How to edit directives previously entered?

Question

I am new to CDAP / Data Fusion. I have created a preparation / wrangler which has included a set of directives. I find that I now wish to edit these previously entered directives but can't seem to find out how to perform this task.

For example, in the following screen shot, how might I use the UI to change the data type for the quantity column to be a float? My current technique is to delete directives 4, 5 and 6 and re-enter but I have to believe that there are better editing techniques than this.

Answer 1

Clicking on ‘x’ will delete a directive. You can’t delete only one from the middle.
