Question about item "use" macro

So I’m getting tired of clicking on all of my BofA fish hundreds of times to get my aromatic fish oil. I made a macro that’s: “/use Mauve Stinger” and then just copy/pasted it till I ran of characters to use. It works to convert 13 (I think it was) fish into oil with just one click of my mouse.

I was wondering if there’s a way to “use” all of the Mauve Stinger in my bags with a single click.
