Choose A Default Music Source & Library Memory

I use Rekordbox exclusively for DJing. Every time I want to add a track to a mix I have to navigate to Rekordbox, find the list and track I want and then add. When I close it and come back I have to do all the navigation again just to go back to the same place. My request is

1. Give us the ability to CHOOSE our own default library. Thank you for the DJ Studio library but for my use case it’s useless.

2. Give us memory in that section so that we don’t have to repeat the same steps every time we need to add music.

Thank you.
