Ability to remove items programmatically from the collection of files for upload

Is it possible to programmatically perform actions on the uploader, such as to remove files, rather than having to click on the remove button on each uploaded file?

ADMIN EDIT

Might be related to the ability to have initial files shown in the list: https://feedback.telerik.com/blazor/1485660-initial-files-in-blazor-upload.

At the moment, you could try using JS Interop to loop over the list, determine which file you want to remove and .click() its remove button. Here is a basic example of getting the buttons to click the second one. You could traverse the DOM to get the file name, or you could keep a collection of the files to use indexes in a fashion similar to this example.

@inject IJSRuntime _js

@* move this script to a correct location it's here as ahack to make the snippet shorter and easy to copy  *@
<script suppress-error="BL9992">
    function removeSecondFile(){
        var deleteButtons = document.querySelectorAll("li.k-file button span.k-delete");
        if(deleteButtons && deleteButtons.length > 1){
            deleteButtons[1].click();
        }
    }
</script>

<TelerikUpload AutoUpload="false" SaveUrl="my-endpoint"></TelerikUpload>
<TelerikButton OnClick="@RemoveSecondFile">Remove second file</TelerikButton>

@code{
    async Task RemoveSecondFile()
    {
        await _js.InvokeVoidAsync("removeSecondFile");
    }
}
