Cross-section Custom option

Hi. I am using OpenRoads Designer now, I used PowerGeopak SS4 before this. In SS4 version, while specifying station ranges for cross-sections, I could use 'Custom' tab instead of 'General' tab if I need sections at irregular intervals, or at random stations where I need to show structures, or even a skewed cut section. Where is that option in OpenRoads Designer? Does it even have that option?

Thanks,

Ronnie
