How to get node info of a tile?

[SaIem]

As the title suggests, is there a direct method to get the task associated with a tile? I know there something similar to determine whether a tile is land tile or not using IsLandTile, but is there a function to return the node ID tied to a tile? The only solution I have been able to get to work is using the encoded topology data of savedata to reconstruct the tile map using the polygon vertices of nodes and using this to approximate whether a tile falls in the bounds of one task or another, but I wonder if there a simpler and more accurate way to just get the node info from x,y tile coordinate? Hopefully I overlooked something..
