Multiple TP/SL Bracket Orders

Hi, could you add multi-target brackets? I need multiple TP/SL levels with the ability to set contract size for each target and SL. Limit orders remain active if the SL is hit, whereas bracket logic cancels all remaining orders automatically. This is important because with standalone limit orders I can’t leave the computer unattended—if the SL gets hit, those limit orders stay open and can fill later unless I cancel them manually. Thanks
