File Upload Progress Bar

Support
#1

Is there a way to show the progress of the file upload from temporaryStorage to fileStorage. I dealy an event listener that can update the UI with the progress of the upload

Change and set a custom File Name -> FileStorageUpload?

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<window xmlns="http://jmix.io/schema/ui/window"
        caption="msg://sampleScreen.caption">
    <layout>
        <fileStorageUpload id="uploadField"
                           fileStoragePutMode="MANUAL"
                           showFileName="true"
                           showClearButton="true"/>
    </layout>
