[Kenwood] Rigblaster?

[ImNJax]

I have a TS2000 connected to my laptop computer by a serial cable and I am
using MixW software. I am using an audio cable to connect the speaker output
of my laptop to the mic input on the front of my TS2000. (The serial cable
recieves the incoming signals and displays them on the waterfall. It also
switches the ts2000 to transmit. If it can send the audio to my radio, I
don't know how to do that). In order for me to use phone I have to switch
out the audio cable for the mic. Other than constantly switching the audio
cable and the mic, how would something like a Rigblaster benefit me?
