Using WKT Polygon with GPS points on icon maps

I'm using icon maps for vehicle tracking using gps points. I have a Geofence polygon. I need to be able to visualize whether the vehicle crossed the geofence and how many distance it travelled.

For this I used WKT object and GPS points in same table to display both Polygon and points together.

Polygon Included when first point of slicer selected

But since I need to filter time of day if I apply a filter and apply custom time the polygon would disappear.

This is because I'm using minute of day as the slicer and the polygon is in first point only. 

Polygon not Included when other points of slicer selected

Is there a method to always show the polygon, while using the slicer.
