Hi @mizanvai — yes this is possible but, unfortunately it’s not very straightforward. I’m planning to do a tutorial on this soon but, in the meantime, you can have a look at my recent post here:
And you can take a look at how we handle the new bulk edit feature here – you could essentially just adapt that code for .NET. The key takeaway is that you will need to move the submission’s current instanceID to a new deprecatedID and then create a new value for instanceID – you can read the code comments here about that.
Once you’ve done that, you can submit the data in the same way as I do in the linked post.
Here’s a draft tutorial on submitting data through the API that still needs to be refined a bit:
Hope that helps.
