New User Question

As the title says I am a newbie. I am amazed at how far Linux gaming has come. I recently decided to load Lutris (so I have the newest version) on my Linux PC (Manjaro) so I could run Guild Wars 2. The install was perfect and the game also runs without problems. Great work Lutris! I still need to load arcdps and blish hud and will Google a solution. I tried to Google this question and did not see an answer.

Is there away to load an executable file before running a game?
