Use merge properties as macro

GENERAL
1

I can use any property or instruction by e.g. using ${-buildpath}. It appears that this does not included other namespaces e.g. if have something defined like -buildpath.fizz: fancy.bundle. Do we have any way to reference this as merged property?

You can use wildcards in macro keys:

     ${-buildpath*}

It is a lot more expensive though
