Change the type of ranging shceme on EVK1000

there’s somehing I’d like to ask about EVK1000(DecaRanging,DecaRangingPCbased).

I know that there are two types of ranging shceme,SS-TWR and DS-TWR.
And DS-TWR(three message) is implemented for software of EVK1000.

(1).Can I evaluate EVK1000 by shceme of SS-TWR?

(2).How can I do (1)?
Is the Application or software for SS-TWR prepared?
Please tell me the procedure of the details to evaluate it.

thank you.
