Calculating Median value by orders

I want to calculate the Medain for all my orders, but the orders are split into separate line by products. Please look into the table below. 

I want to group all the orders and then calcualte meadian for the entire table. The median for the entire table should be {31.05, 10, 34.10, 47} = 32.575 ~ 32.58

I am using the following code to acheive this.

Median Order Value = 

VAR IncomingSales = SUMX('Sales', 'Sales'[Quantity] * 'Sales'[Price of Product])
VAR SalesByOrder = SUMMARIZE('Sales', 'Sales'[Order_ID],"LineSales",[IncomingSales])
VAR MOV = MEDIANX('SalesByOrder',[LineSales]

RETURN MOV
