Chart Viewer with switching assets

I'm developing a forex strategy which contains all 28 majors and crosses of the G8 currencies. I don't want to train on each currency pair separately, but rather have one single strategy with one set of parameters. The asset to trade with is selected by technical currency strength and fundamental data. For debugging, I would like to use the chart viewer with . However, it seems, that the chart viewer will only show one currency pair which can't be changed during the test run. Is that correct and if so, is there any other possibility to deeply look into the single trades?

Select the currency with the scrollbox, then click "Result" for displaying it in the viewer.
