CCS/LAUNCHXL-CC1312R1: long range low bps profiles not available for CC-1312R?

Tool/software: Code Composer Studio

Is there a reason lower data rates for the 1312 is not available in the Smart RF studio and from the EasyLink_init? The following snippet blocks from using it.  

case EasyLink_Phy_625bpsLrm:
if(!(ChipInfo_ChipFamilyIs_CC26x0()) && !(ChipInfo_ChipFamilyIs_CC26x0R2())
&& !(ChipInfo_ChipFamilyIs_CC13x2_CC26x2()))
{
useDivRadioSetup= true;
rfConfigOk = true;
}
break;

We need 625 bps long range profile with DSS SF8, just like the 1350.

Thanks,

Ratin
