Sampler

I am new to using the interface 2, I have been using serato for the last 12 years, so im learning and if there is a way to do what I am asking then please let me know.

So, when pressing the samples during the set I would like to have an option of master for the samples, currently the only options are channel 1 or 2, the option of master would mean that both channels play the sample. My reason for this is that it is faster during mixing and I done have to worry about touching the computer when i want to put a sample on
