Add option to start blender using custom command (not only custom binary)

[zepadovani]

Hi,

using Manjaro/Linux with a NVIDIA card, I usually start apps that will need to use the external card by running "prime-run <binary_path>". Is there a way to add such an option in the extension? That would be really usefull to take profit of my card features while using the extension...

Thanks for any tips related!
