Spotfire Ideas Portal
Sometimes I like to mark data in a polygon shape. I use Spotfire's Lasso marking for this, which is nice, but in some cases it would have been easier to make exact markings using a polygon marking mode to exactly click on the points of the polygon.

Future Consideration
There is a way to achieve this behavior today using the following method:
Use the Points in Polygons data function available from TIBCO Community. This data functions will detect which markers are located within a feature layer. The function will add a new column to the marker layer data with features IDs assignments.
Create a relation between the marker layer data and the feature layer data based on the new column created by the data function.
Now when you mark a polygon shape in a feature layer on a map chart, the markers inside it are marked.
