Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Target 1 Machine monster you control; apply the following effect depending on its battle position. ● Attack Position: Special Summon 1 "Morphtronic" monster from your Deck with a different name than that targeted monster, then place that targeted monster on top of the Deck. ● Defense Position: Change that targeted monster to Attack Position, and if you do, Special Summon 1 Level 4 or lower Machine monster from your hand. You can only activate 1 "Morphtronic Converter" per turn.
