Customise the step forward and backward times on tizen

Can the amount to skip forward and backward be adjustable in the tizen player. I find that if I have the step forward set to 30s but the step back set to 10s this makes it easier for example to step past a TV series intro or something like that. Having symetric forward and backward just means that I either end up past where I want to go or before and I have to watch to that point.
