Possible to provide ordering in grids similar to what is available in Appian Designer?

Here is a rule I wrote up quickly, which I called swapElementInArray(). It takes in three arguments: array (any type), index1 (int), index2 (int). It will take in the given array, and swap the elements at the two indexes, and then return the new array.

with(
local!element1: ri!array[ri!index1],
local!element2: ri!array[ri!index2],
local!indexArray: {ri!index1,ri!index2},
updatearray(
ri!array,
local!indexArray,
{local!element2,local!element1}
)
)
