[SQ4 B2] "Randomize Slippage from..." < 1 not possible, says "Minimum value is 1". Why?

As the topic says, I would like to set a randomized slippage range of 0.2 to 1 pips in the "Robustness tests".

Why can´t the minimum be < 1? My average slippage as logged by my Excel spreadsheets is about 0.7 pips with my broker. So I would like to be able to randomize the slippage with values < 1 for the minimum. This was possible in SQ 3.8.1, why not in SQ 4? Bug or intended to limit us like that? If intended, please remove that minimum of 1, most brokers have sub 1 pip slippage nowadays and I want to correctly replicate this in SQ4. Thanks.
