I recently developed a workflow for using macros to insert sound effects into my timeline, and although it has its quirks, so far it's working great. The one limiting factor at the moment is that I have to manually select which track is currently active for Source Patching in order to utilize this workflow, so if I want multiple layered sound effects, I have to change the active patching track. If Excalibur would allow me to select which track I currently have selected for Source Patching, I could easily program my macros to cycle between 3-5 tracks every time a sound effect is placed so that layered sfx would be less of a hassle.
