I do have all the operations implemented, just decided to push them one by one so they are not dependent on each other and it's easier for the merger to handle ;).

We are also interested in this feature and thought about implementing it our-self and bringing it upstream. And were happy to see, that there was already work done for that.

What is the current status of this? I see the List Mappings is already present. What about the other calls?

@emilmaruszczak Is it still your plan to create PR for them?

[emilmaruszczak]

@shaardie The logic and unit tests are implemented, I will PR them in shortly, after adding the acceptance tests.

@emilmaruszczak looks like you've implemented it all. Is there anything left, or can we close this issue now?
