Specify output column name in reusable transform

[dherls]

I have a sequence of steps that I want to apply to a few of my columns in my pipeline. I would like to make it re-usable, but both custom expressions and transforms do not give me what I want.

• Custom expression - I would need to nest each of my steps as inner calculations, and maintaining a 6+ nested expression sounds horrible.
• Custom transform - there is no way to specify the output column name of my transform.

Ideally I want to input my column, and have all of the steps run, and replace that same column with the new value.

Is there a good way to do this in PB today?

Hey @dherls, you’re correct about all that you described. Custom expressions and custom transforms as they are today don’t do what you’re looking for.

This ask has come up before though a few times so I will track internally with the team. Our future library editor could solve this, but there may be something simpler we can do before then.
