In-app-download of transformation grids

In some countries, so-called transformation grids are required for the transformation of geodata into the country's own coordinate system. In Austria, for example, for the transformation from the GPS coordinate system ETRS89 (EPSG 4258) to the national coordinate system MGI Gauß-Krüger (EPSG 31254) the GIS-Grid from Bundesamt für Eich- und Vermessungswesen (https://www.bev.gv.at/Services/Produkte/Grundlagenvermessung/GIS-Grid.html) is necessary.

These grids currently have to be loaded manually onto the device used with VertiGIS Studio Mobile, for iOS for example via iTunes. The software FieldMaps for ArcGIS can download the transformation grids directly within the software (in-app-download). We would like to have this feature in VertiGIS Studio Mobile as well.
