Add send control to drum rack?

[binarysun]

So I have my two default return channels/tracks in a project. And a Drum rack on a track. While browsing through the drum rack on push I saw that I can for example adjust the "send 0" for my Hat that sends some of the signal to Return A because this send seems to be "pre-connected" in a standard drum rack. Now I want to also send the Hat to Return B. Can I create a "send 1" that connects to Return B via Push or do I have to use the mouse to add it to the drum rack? And how would I do it anyway?
