Can I add "add row" to this table row drag/drop/delete?

Can I add "add row" to this table row drag/drop/delete?

Hi there everyone!

I'm integrating this table drag & drop into one of my forms.



You can see with my form that I've also included a form element right below it that allows me to add new specs, in addition to the current ones that I am now able to reorder.

I would, however, love to be able to nix the second "add" specs and simply click a button to add a row onto the draggable table.

Is such a thing possible and if so, how might I go about it?

Thanks for your time!
