Im surprised this hasn’t been done already. But there should be an “toggle option” in your Army Camp to Automatically filter your army to your designated Army. This could get quite expensive however, I find that when I’m farming and decide to raid with a portion of my army. I have to manually fix my army camps. As my second army is then out of order and adding troops to my next raid that I don’t need. It’s frustrating because there is a simple solution to it. Possibly adding a filter order to prioritise what troops you want to train first to last. But again MINOR fix will help the efficiency of attacks.
