Indicator for values selected in slicer

Use case:
* There are multiple slicer controls on the screen that allows multiple values to be selected for each slicer to filter a result data grid.
* Each of the slicer has multiple values so the values in the control are scroll-able.
*

Problem:
* There are no visual indicators on the slicer which indicates in a glance which slicer/filter has been applied to the result grid.
* Have to click on every slicer to see if values are selected
* If the list of values are long, have to scroll all the up and down to look for selected values

Suggestion/Solution:
* Show a Funnel/Filter icon in front of the label of the slicer control. Example: [Icon] Slicer Label
* Allow the user to select the color of the icon (to match the color theme)
* Display count of items selected in the slicer. Example: [ 5 ] Slicer Label
* Sort the list in the slicer to show the selected values grouped at the top, then followed by the non selected values. This way the use does not have to scroll all the way up and down to look for values that are selected for the slicer
