Fib Extension for Marketscope 2.0?

Hi all!
Is there anyone out there that can help me with a FIB EXTENSION indi for FXCM's Marketscope 2.0? At the moment ,the Marketscope 2.0 charting system only provides one with FIB RETRACEMENTS and FIB TIMEZONES but I like using FIB EXTENSIONS for trading targets (exits).

Any help will be much appreciated.
Thanks.

A trader suggested using Marketscope 2.0's Fib Retracement, but line it up 'the other way' or 'upside-down' and it works just as the Fib Extension on MT4. I tried it and it fails miserably!! The Fib Extension targets don't line up with 'Upside -down' Fib Retracement levels, even when you adjust the levels.
Thanks, anyway.
MT4's Fib Extension has 3 points that can be adjusted, wheras Marketscope 2.0 only has two.
