Is there a way to convert existing assembly items to be matrix children of a Matrix Assembly Item parent? I created the matrix parent, included all necessary components, created the options lists and fields, populated the matrix parent with a default child via the UI, now when I run a scheduled script to set the parent (matrix assembly id), matrixtype ('CHILD'), and matrix option fields on the stand alone assembly item, those fields get updaed but the assembly item is not listed in the parent's Matrix Item sublist?

be weary of trying to do something in script that you cant do in the ui
