Filtering Activities on the Map View

Content

Does anybody know if there is a way of filtering activities in the map view when looking at activities assigned to a bucket or another resource. As per the screenshot below, I can currently see all activities on the route which are outstanding in OFSC. A lot of these activities are for different buckets and require different skillsets for the resource that i have selected.

If its not possible to filter these activities, i feel it makes the map view much less useful and efficient to use. 

Ideally our users will be able to filter on these activities and based on the filtering criteria, the map view will show jobs which are eligible to be reassigned to the resource selected.
