cTrader Sample cBot (small addition)

cTrader has inbuilt cBot 'Sample Trend cBot'.

If I run multiple instances of this cBot (same symbol, different timeframes), it shows same Label 'Sample Trend cBot' for all positions opened through different cBot instances.

This creates problem because bot can't differentiate which open position need to be closed.

How can I add new parameter 'Instance_Name' to cBot?  It will allow me to write different values in Instance_Name parameter for each cBot instance, to differentiate open positions.

I am not expert in coding, so please update it in the below code.  Thanks
