Finally got this one working...

Inspired by 2016 SOLIDWORKS Help - Best Practice for Configurations with External References

It will configure your parts to match the assembly

Works entirely by pre-selection.

Select the Components and Configurations you would like to Apply

If no selections are made the macro assumes you want everything...

..but will ignore hidden components.

Not Fully Tested ... Caveat Emptor
