The ability to disable or weight (+/-) the instance prompt when using a dreambooth trained model.

Currently the instance prompts gets injected without user control. It would be nice to have more control to allow for adjusting how much of the custom instance is evoked during generation. My idea (hope) is, that this would allow weighting dreambooth isntance "strength" against the prompt. Allowing the likeness of the resulting images adhere to the prompt more than to the dreambooth trained instance.

Hope this makes sense!
