[request] way to change multiple devices?

[RdWing]

Hi, Thanks so much for creating LosslessSwitcher. It works great! I am primarily a headphone user, and I generally use a parametric EQ to equalize my headphones towards the Harman over-ear target, using @Oratory1990's great settings. (See the AutoEQ project).

In order to accomplish this, I use Blackhole to create a virtual audio device that pipes audio to AULab, which hosts then outputs to my dac. So, I need to be able to switch two devices, the Blackhole sink and the dac itself. Is there a way to accomplish this now? And if not, would you consider maybe adding multi-select to the Select Device menu? Currently I am frequently ending up with mismatches.
