Open with Custom Button

Would it be possible to have a way to open this menu with the Custom Button integration? I also bought that one and wanted to be able to open it via a button press even if I am not at a work bench.

Is this possible?

Sent you edited version in private message. It wont look good as when you open it in workbench, I did what I could. 
Please make sure you read description before you buy plugins, it's not always that easy to add something based on requests.

Oh, wow thanks, I was just wondering if it was possible, I wasn't expecting you to change the code for me I just wasn't sure if there was a hidden command or something. But I will use it since you modified it for me, thanks!
