For ArcGIS Pro Raster Symbology enable "lock" statistics from custom view extend to apply for the whole image

Idea created by nangka on May 26, 2018

    I work a lot with Satellite Imagery. For an optimal/useful raster display I need to change the default stretch (to a custom strech). In ArcMap it was possible to get very good parameters (statistics on what the stretch is based on) by playing in the symbology window with the "from current display extent" (DRA Dynamic Range) and then "lock" this by choosing "From custom settings (below)".

    Unfortunately this seems not to work in ArcGIS Pro (tested on 2.1.2 and below). 
    I would like to propose to add (back) this functionality to ArcGIS Pro as to be able to "lock" statistics for the raster display from a custom view extend.

    I like ArcGIS pro, but missing this feature makes it next to useless for me for creating maps with imperfect satellite imagery (esp. if the imagery contains some clouds or haze) as a basemap.

    This should be an easy fix as it would just require to store the DRA (Dynamic Range) imagery statistics from a custom view extend and copy/apply them for the whole image.

    How to "lock" a DRA/stats (Dynamic Range) for a custom view extend ArcGIS Pro raster symbology?
