You can find attached our workflow, which we created with all of your helpful comments.
Dynamo automatically place every legend using the coordinates we are giving as the legend center coordinates.
We are trying to insert some node so Dynamo can understand that the given coordinates are from the upper left corner from the legend (where the title is), but we can’t find such packages.
