Which REST API call to use to remove line items having validation errors?

Summary:

The all or nothing approach when importing a .csv file or creating a request using .xlsx is causing issues.

However, is there a way to check which records failed in a request, delete those request items from the request and submit the request in EDMCS using REST API?

There are multiple responses in the "REQUEST" REST API, how can we leverage those to achieve the above requirement? This will help us do away with the all or nothing approach especially when we are receiving data from an upstream system like PPM and the users in PPM would need time to repair those bad records.
