Prepare data step in pipeline

[bicarlsen]

Is there some sort of "prepare" step in the data pipeline? e.g. Form data needs to be prepared before submission where the calculation is expensive. I can't validate the form until the data is transformed though, and the same transformation needs to occur for form submission.
prepare -> validate -> submit

Right now it seems like I would need to transform the data for both the validate and submit steps.

(I'm new to the community, so still not familiar on how exactly to look for these things. Sorry if this is a duplicate)

Perhaps you can perform the preparation before calling form.handleSubmit?

@LeCarbonator How would the prepared data then get passed through the data pipeline (i.e. to the validator and handler)?
