Well, I think theres a way to specify a different file for each set of settings,

But, if I understand you correctly, you are looking to be able to call xmr-stak similarly to the way ccminer is called?
XMR-stak is a bunch different than most other miner apps in the way its configured......   I would need to figure out a LOT of this guys code locations and structures to rewrite how it works... and I am probably not gonna have that kind of time anytime soon to be frank.


The main premise that makes XMR-stak nicer than the way you launch ccminer; is:
Once you get the host machine set up, you do your first run of xmr-stak, let it take in configs/settings and bench the devices, and you simply need to only call xmr-stak.exe to launch from then on.  It creates its config .txt files to suit your pools config and devices.

If you want multiple instances for multiple devices;  you need multiple folders per device with a copy of the executables in each...   Bench and first run each as normal;  but comment out the devices in each folder's instance/config .txt to only use the devices you wish to use per-instance....



If I am totally wrong above about what you are trying to achieve, LMK... Ill do my best to help.
