Set/get LR runtime settings from script


We have a requirements to run simultaneously the same script with different bandwidth speed for mobile project.

I found out that I can call the same script multiple times from the same Controller scenario, where each call has different runtime setting.

Can I get the setting from the script to split responce time by bandwidth speed?

Can we change Speed Simulation runtime setting from a script like we do it with Download Filters by using LR function?
