Hi! I'm new to QC and I'm having trouble trying to use IB brokerage model and some other custom models as IB model doesn't include slippage and other things. I read in the docs that Brokerage models override any other models you may set for a security but I want to know if there is some way to implement a custom model while keeping IB model.

If anyone has done it, i would appreciate the help

Thanks!
