How to change the altitude of multiple roads and define lane access?

I have the following questions about RoadRunner:

1. How can I change the altitude of multiple roads at a time?

2. How can I define the lane access of a lane e.g. define a lane as restricted to buses only.

Changing the altitude of multiple lanes at a time

You can adjust the height of multiple roads using the "Road Height Tool" in RoadRunner 2021b. First select multiple roads and their corresponding control points. Once selected, simply dragging up or down to adjust elevation is possible while using the "Road Height Tool". There are a few ways to select multiple roads, including, drawing a box over the roads by left-clicking and dragging your mouse, holding "shift" while left-clicking the roads, and using "ctrl + A".  

Define the lane access of a lane

You can use the "Lane Tool" to select a "lane type" for the selected lane. This can be something like "restricted" or "parking". The lane type will then be exported to "OpenDRIVE". You can also define custom lane types in the OpenDriveAssetData.xml. Refer to the link below for more information.
