Is it possible to 'Backtest' Renko Bars in mt4?

Is it possible to 'Back test' a method of Renko Bar in the 'Strategy Tester' of the MT4?
I have looked for such Offline option but didn't get one.
Also, if such offline chart got checked in ST, then how much the accuracy can be?

Thanks in Advance

The accuracy is poor, if you use the default (i.e. non-hacked) ST behaviour, because of the artificial open/close candle prices in Renko. So not even strategies with "use only open prices" work reliably. I do not know if there is non-standard solution available, you would need probably to ask some coder.
Nevertheless if you still want to test your offline chart in the standard ST, here are the free scripts I use:
for 509: backtest_helper.ex4
for 600+: OfflineTestHelper.ex4
