Multiple device mass import?

I am trying to find a way to speed up adding active devices to our system as we add 50 or more at a time and doing them individually takes an unacceptable amount of time.

I am not seeing any way to do this but have to believe it is possible or could be with the proper converters or update to the system to allow a mass import.

I can see either a tool that takes a spread sheet and splits each line into a separate WLP file for importing or a mass import feature added to the system.

If I am missing a simple way to do this, I apologize as I did not see it.

Thank you.
