Player spawn location?

[Parzival2020]

I dont think this is possible, however let me ask anyway

 

I am working on a mod with a custom map.  The map is completely featureless, no towns, tree's, roads, POI's etc except for 1 trader.

 

I would to ensure the player spawn near the trader or if thats not possible, if there someway of creating an item that would allow them to teleport to the trader, but a one time use only?
