Allow custom manipulations to data during a data deployment
Export the selected data source in a CSV file before deploying, in order to allow custom manipulation. Then allow the import of that CSV to destination - functioning like a more sophisticated Data loader.
What sort of manipulations would you like to make in the CSV?
It'd also be great to hear what data masking options are missing at the moment.

This will help with masking fields not supported by the data mask or where data mask options are not suitable to use case.
