Additional Command-line Switches option in DS 7.1?

We are looking at the viability of transitioning from 6.9 to 7.1 DS and we are running into some apparent feature diconnects. One big one is the lack of a location within 7.1 script tasks to pass additional parameters, via the "additional command-line switches" task option.

I haven't been able to find any information around how this is dealt with in 7.1. I am guessing there must be some simple answer that I am just not seeing.

Anyone have any input on this?

Thanks.
