That's not possible if you use the gst-launch-1.0 command line tool.
This tool is primarily for debugging purposes.

I would recommend you write a little C application or python script and
use the gst_parse_launch() API to create a pipeline from a pipeline
string if you like. You can then modify things on the fly in your own
code.
