is it possible to change Listview rows position/number/index through listview built-in funtions, guicontrol or control commands?
(Obs): I don't want to use the delete/re-insert row method!
Right now I'm using the workaround below, but if there is a better way to do the same thing, please post here!

Loop 10 ; Load the ImageList with a series of icons from the DLL.
IL_Add(ImageListID, "shell32.dll", A_Index)
Loop 10 ; Add rows to the ListView (for demonstration purposes, one for each icon).
LV_Add("Icon" . A_Index, A_Index, count++)

;"1" column 1
;"Sort", Immediately sorts the column in ascending order (even if it has the Desc option).
;"Float" For sorting purposes, indicates that this column contains floating point numbers (hexadecimal format is not supported). Sorting performance for Float and Text columns is up to 25 times slower than it is for integers.
;"Integer" sorting instead "Float" sort prove to be buggy (not accurate)
;"Left", Left-justifies the column's text
;Update rows index numbers
loop, % LV_GetCount() ;the function returns the total number of rows in the control
LV_Modify(a_index, "Col1", a_index)
