Way to configure additional values in Explorer Results Window

[MarietteShin]

We use ArcGIS Pro 2.2 to publish our Mobile Map Package (mmpk), which then gets consumed by Explorer for ArcGIS.

Right now, there is no way to configure what value(s) get displayed in the Explorer for ArcGIS results window upon a search.

For example, when we run a search on a Corrosion System ID in Explorer, what we are hoping to see displayed in the Results Window are all of the Corrosion Test Station feature IDs that are under that System ID.  Instead, what we currently get returned in the Results Window are all of the search result items but with the same System ID value displayed for all of them in the results window. So, our users cannot differentiate one result from the other, and must open up each result in order to determine what its unique ID is.

I would like to see some way in ArcGIS Pro 2.2 to configure the value(s) that get displayed in the search results for a particular feature class/layer (maybe using Arcade?). Then, to be able to publish this configuration to an MMPK that honors that display. So, in an ideal world, our System ID search would return not just a list of features all displaying the same System ID, but also show the unique Corrosion Test Station ID under the System ID.

Thanks.
