Custom slicer for selecting all found-by-search values with one click, implementation approach?

Hello,

I am new to PowerBI and trying to get a grasp of the general concepts, naming etc.

I would like to implement a custom slicer with the following additional functionality:

When a search is executed in the slicer there should be a way to select all found values with one click rather then have to hold CTRL and selecting them one-by-one.

From what I read on the internet there is no way to achieve this with out-of-the-box functionality in PowerBI. There is also no way similar to holding SHIFT and selecting the first and the last values to automatically select everything inbetween.

Can you please point me in the right direction to dig for info, what are the keywords for this to google for? What is the proper terminology in PowerBI? Is it even possible and what would your general approach to this task be?

Is Advanced Filter API and the aproach used by this example the right direction to go?
