File copy step - target name as variable

We have wireguard conf files that are on a server in the format of %computername%.conf.  These files need copied to the target computer.  Using the file-copy step I'm unable to use the variable of %computername% because it's set to the PDQ deployment server.

It would be helpful if PDQ had an environment variable that was the name of the target computer. 

For now I'm using a command step and just running the copy command.
