Is it possible to prepend options to the command?

[Realitaetsverlust]

So first of all, the application works great. Has saved me a lot of nerves. :) However, I'm having a small feature request:

On my laptop, I have two GPUs, an internal iGPU from intel and a nvidia GPU. The nvidia GPU is usually on standby unless I specifically request an application to be rendered with it. I do this by adding prime-run in front of the command in steam, so it would look like "prime-run %command%".

Now, this obviously doesn't work in steam as the application that is started is the notparadoxlauncher, which in turn starts CK3 in my case without the options.

Is it possible to create a way to not only append options to the game, but also prepend? Or just give us a way to use a "steam-like" %command% so we can basically create the launch command ourselves?
