Increased WMS support for VertiGIS Studio Web

We need increased WMS support for VertiGIS Studio Web.

We want a out of the box solution that allows both functionalities for this WMS in GeoWeb( a VertiGIS produtct): https://prorail.nazca4u.nl/mapserver/mapserv.exe?map%3DD:\websites\kaarten\bedrijven\prorail\mapfile\prorail_wms.map

1. To not show a result (html) whenever an identify operation takes place outside of the geometry of the layer. (see picture) > main issue. 

2. To return multiple results for an identify actions when there are multiple matches. Currently we have implemented a workaround that at least gives us back multiple results, when there are multiple matches (just added featurecount to the URL), but this can not be combined with workarounds that are possible for first other problem.

Apparently it is currently not an option due to security reasons. 

In other software this is however possible and seems to work most of the time, such as ArcGIS Pro and ArcGIS Online
