Can you move multiple TOC entries at once?

I've editing some garbage auto generate epubs, they tend to have single layer of TOC which is hard to navigate. So I change them.

But here is the thing, it seems that you can't select multiple entries in Editing TOC window, making it hard to edit.

So am I doing it wrong or Sigil just can't do that? Currently I'm directly editing nav or ncx, which is annoying and tend to need several tries to make it correct.
