PlotPolesNumber = size(PlotPoles[@player("name")]) + 1
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
PlotPolesNumber = size(PlotPoles[@player("name")]) + 1
PlotPoles[@player("name")][PlotPolesNumber] += @location(@transaction(transaction, "after"), "array")

I am trying to create a map which is named after the player, will first contain the blocks location during a place event. Then later will also contain a list of players names which will be in the original players party/group.

I want it to look something like this:
Plotpoles = {"Ghaz_ranka" : {world, 0, 0 ,0}, {"Hawk_eye0091"}, {"AnotherPlayerName"}, "RandomName" : {World, 0, 0, 0}, {"AnotherName"}}

Using these maps I can first check to see who the owner of the "PlotPole" is then check if a player is within x,y,z range of the coordinates and then finally check if the player is in the party/group.
