Feature request: Add manual edit step(s) in the recipe

**Is your feature request related to a problem? Please describe.**
Perhaps this is already possible, maybe I just cannot find it. I would like to be able to first do some processing then be able to manually edit that processed data and then further process it.
For example:
Step 1. Decode Base64
Step 2. Edit decoded text
Step 3. Re-encode the edited data to Base64

**Describe the solution you'd like**
I would like to be able to add a step (or more) between the input and output fields where I can edit text manually.
