I use custom_attributes in VMWare to document the server description and would like to use it in Host Auto Discovery as a property host.alias. Unfortunately, this is not possible so far, after the source selection "discovery.results.custom_attributes" no selection of the attribute to be used is possible.
When adding Marco Conditions, a popup opens at this point to select the property.

It makes sense to include this selection in the property selection as well, so that the evaluation of arrays is also possible in Property, as custom_attributes.
