Download a single invoice vs multiple behavior

I have a table which display all of the user's outstanding invoices.

Currently, the user is allowed to select one or multiple invoices that they can either download (PDF format) or pay all at once.

I would like to add the ability to quickly download a single invoice. They are able to do this currently by just selecting the invoice they want to download and clicking on the download button up top.

I came up with 2 options:

(A) Add a download button next to the invoice numbers:

(B) Collapse the Copy button AND Download button into an ellipsis menu.

I think this is a cleaner approach, but if multiple invoices were selected AND the user opens up one of these ellipsis menus, it might suggested that they are about to download multiple invoices instead of just one?
