How do I backtest my EA on 10 min timeframe on mt4?

[qwertyuiop1]

I have a 10 minute offline chart displayed on my mt4 platform. I have my EA dragged onto this chart as per usual

I now want to backtest this strategy - but the timeframe drop down menu on strategy tester only contains the usual 5 min,15 min,30 min etc.

Does anyone know how to backtest my EA on the 10 minute chart?

Or can anyone even confirm if such a thing is possible? (Surely it is seeing as the 10 minute chart is viewable)
