How to change the Turnout (for Indian Broad Gauge) Radius & Angle in Bentley Open Rail?

Hello,

I am designing a yard in Bentley Open Rail and for that i want to give turnouts of 1 in 8.5 but the radius is fixed for the 1 in 8.5 Turnout in the feature definition and therefore, i want to change the radius and angle of that turnout. So, kindly advise me in this matter as earliest.

Thank you
