I am interested in tithing some of my profits but would like to automate.  Here are my thoughts...  

• Claymore using dual mode - I do not see setting to allocate 10% resources to a specific pool.  I was thinking that -dcri option would be my best option, but am not sure.
• sgminer using quotas - This would be perfect because I could then allocate 10% to pool_a and 90% to pool_b.  But I am having issues setting up the command line.
• GPU assignment - Not sure if this could be done, but there might be a way to specify a GPU to a specific pool.  This method would work, but since I have 6 GPU's, devoting one GPU to a specific pool to tirhe is more than I wanted (1/6 is about 16%).

Are there any ideas or suggestions for me to accomplish this?

TIA!
