[SpecMap] Automatically add and update cards from the linked Slices/UA (the "children" of the linked Iteration or linked UA Work Item)

Please automatically add and move cards from the linked Slice and User Activity in the Backlog. This would include:

* Automatically add missing cards to the map from the linked Slices/UA (the "children" of the linked Iteration or linked UA Work Item)

* Automatically move existing cards on the map to match the backlog when mismatches between the map and the backlog is detected (ex: If I changed the iteration or the parent of a child in the Backlog in Azure DevOps then when I go to SpecMap, the map would automatically sync (cards for the Slice/UA updated).

* Also please consider prioritization of cards using the map and reflected within the context of the iteration/slice and UA in the Backlog.

Thank you.
