This still needs additional testing.

Added a few commits to @MrMarkW's PR, the code is now working well. Can we consider adding this in?

[MrMarkW]

@blajoie Thanks for the changes. I'm not currently working a project related to this at the moment, but would love to help you push it through.

To add additional weight - we have just been looking at tuning our ebs volumes provisioned using this tool. We too would be interested in making use of this additional funtionality.

(@MrMarkW, @blajoie many thanks for the leg work)

1. Could we have help in reviewing/merging this change?
2. What would be the expected timeline for creating a 2.4.7 release?
