Open pipeline in gst-launch format directly from command line

Describe your RFC

Instead of copy the pipeline, open gst_pipeline_studio, press Open pipeline (Ctrl+P), and paste it.

The goal is be able to open a pipeline in gst-launch format directly from command line. In other words, replace gst-launch-1.0 by gst_pipeline_studio in the terminal and be able to debug the pipeline.

Expected Behavior

 $ gst_pipeline_studio multifilesrc location=bus.jpg ! \
 jpegdec ! videoconvert ! \
 onnxinference execution-provider=cpu model-file=model.onnx \
 videoconvert ! autovideosink

Additional Information

Open pipeline doesn't work for multi-lines pipelines:
