toc entries - anchor from part of the beginning of a paragraph

[Rfromearth]

Hello, I'd like to achieve the following:

I have a paragraph like this:

1.1 At vero eos et accusamus et iusto odio dignissimos ducimus qui blanditiis praesentium voluptatum deleniti atque corrupti quos dolores et quas molestias excepturi sint occaecati cupiditate non provident, similique sunt in culpa qui officia deserunt mollitia animi, id est laborum et dolorum fuga.

and I want this toc entry:

1.1 At vero eos et accusamus

I can't use

#### 1.1 At vero eos et accusamus et iusto odio dignissimos ducimus qui blanditiis praesentium voluptatum deleniti atque corrupti quos dolores et quas molestias excepturi sint occaecati cupiditate non provident, similique sunt in culpa qui officia deserunt mollitia animi, id est laborum et dolorum fuga.

because the hole paragraph will show up in the toc listing.
I don't want to write

#### 1.1 At vero eos et accusamus,
et iusto odio dignissimos ducimus ...

because it breaks the paragraph.

<a id="1.1">1.1 At vero eos et accusamus</a>, et iusto odio dignissimos ducimus

creates a nice link, but no toc entry.

<h4 id="1.1">1.1 At vero eos et accusamus</h4>, et iusto odio dignissimos ducimus

creates an even nicer link but breaks the paragraph and isn't listed in the toc.

Thank you for reading my comment.
Any ideas?
