Split Market Order Before Sent To Server

 
Is it possible to split a market order before it is sent to the server or are market orders immediately sent preventing any modification before being sent to the server? For example, if a market order for 5 lots has been placed, I'd like it split into 10 market orders of 0.5 lots each instead and then sent to the server. Is this possible? Thanks in advance.

No, not possible! You have to place the order correctly from the start.
 
Don't make multiple orders as they will interfere with each other do to FIFO rules.
