Running multiple custom WADs simulatenously under Zdoom

[EldritchNexus]

I'm using a Mac and playing the uacrebellion wad on Zdoom, and I thought I'd spice things up with F3.wad so that I could fight UAC marines using weapons from the Fallout series. How can I do this? And I mean, so that every time I open Zdoom, these wads will automatically load without command prompts or whatever.

[_mental_]

Drag and drop both .wad files (or even downloaded .zip files) on ZDoom icon.
Application should not be started yet.

It impossible to get rid off the IWAD selection window without using shell or Apple script.
Of course you can leave only one IWAD available to ZDoom but it's quite inconvenient.

Okay. Thanks!
