Hi,
The short answer is no out of the box. Because the browser dev tools are not part of the rendering information that Subject7 has access to.
Would you please state what is that you would like to do, a use case or a real example would be very helpful.
You can possible used Snippet to extract such information using 3rd party libraries such as BrowserMob https://github.com/lightbody/browsermob-proxy
Here is also a reference for using a snippet (Running your own Java code in Subject7)
