Does SolarWinds have any features for Wake-on-LAN (WOL) for multiple computers at once?

My client has the following problem:

Currently, the SolarWinds WoL software is experiencing issues with the Wake-on-LAN (WoL) feature. Specifically, the current process requires scanning the IP/MAC addresses of machines, then copying and pasting them into the interface to wake up each machine individually. Each machine takes at least 1 minute to start up, so waking up 400 machines takes up to 7 hours (from 8 AM to 3 PM), while normally this could be done in 15 minutes with 2-3 people.

Does the software actually work this way, or are there other options that allow you to wake up all the machines at once?
