I think the term you search for is via stitching.
I’m not sure what you mean with the label part. Could you enlighten me?
Sadly there is not (yet) a simple way to add something like this.
I think better via stitching support is planned for the v5 release. But i seem to remember that the part of automatically adding the vias is still missing. (Read it somewhere on the mailing list a few month ago.)
