Key Commands: Sample preview Play button?

When auditioning samples, something I often want to do is play that same sample immediately again to make sure it’s what I want. Why is this not possible without going to the previous or next sample with the arrow keys? Could you please bind the left arrow key to retrigger the sample? Please?

Or maybe make the available Key Commands more robust so we can bind to the sample preview Play button?

I would like to see this in GA too.
