How to insert blank line in auto-generated TOC?

I am compiling to ePub 2, and I am using the Scrivener feature to auto-generate the TOC. I would like to insert a blank line in the TOC. See image below. Is this possible?

I’ve tried several ideas, including the insertion of an empty folder, but no luck yet. Also attached is my test file. Thx.

There’s no way to do this in an auto-generated ToC - you’d need to use a manual ToC for this. With ePub 3 you might be able to achieve this with CSS, but probably not in your case where the contents items are all at the same level.

Thanks Keith.
