Passing altered data to nvinfer plugin

I have several nvinfer plugins in pipilene. For one of them I want to pass modified buffer data (some rotation + custom scaling), but Gst buffer for next plugin must not be modified.
Is it possible?

we are checking internally and will give you reply ASAP.

Whatever modification is needed should be done inside nvinfer plugin - similar to what we do before inference. U can refer to nvinfer source code
