Problem (one or two sentences)

At our company, to prevent information leakage, there is a size limit for uploaded content on the intranet. Therefore, when I use RooCode within the company, the model's context window cannot exceed the company's upload limit. I need to modify the default context window size provided by the model provider to prevent it from exceeding the intranet's upload size limit.

Context (who is affected and when)

In some cases, users need to modify the default parameters of the provider's model.

Desired behavior (conceptual, not technical)

Support user modification of model parameters.
