Jason agreed to add this option but we then realized there would be complications that need to be sorted in RL.
The main issue is any playlists that don't use the standard RL names won't work for modules that have system name checks in them. I implemented a feature on a test setup that will resolve this by allowing any system name to work in general, not just for LB. However, this breaks certain things in RLUI and the RL devs are taking a break from development due to life stuff. Not only that but even if I did update the plugin your system list in RLUI would be a pain to navigate since it doesn't nest systems/playlists so there would be hundreds (or thousands) of entries in the system list in RLUI.
So I would at minimum have to create a tool to configure playlists to work around the RLUI problems. Or I would have to write a complete replacement for RLUI so users wouldn't have to switch back and forth between the two. I haven't decided what I want to do regarding that yet. I'm currently updating all of the modules to use the RL classes and creating a mirrored set that allows for any system/playlist name so that needs to come first, then doing a tool/RLUI replacement, then updating the plugins.
This stuff is at the top of my to-do list but since I do this in my free time I can't and won't give any timeframe. I definitely won't be doing any significant work on it in the next week since Hitman 2 released today
