Treetable Delete Multiple and message

Hello,
https://snippet.webix.com/yya4qpqa

I need the following:
After deleting several items (or a branch with childs) I get several messages (“Entry deleted”), as every id is treated in the Dataprocessor separately.

Is there a way to have the info how many ids are deleted (I would like to preserve the structure “afterdelete” in the dataprocessor as I want to be sure they are really deleted…)

Thanks!
Martin
