I am using the dvc tool to track experiments in my repo. When I run dvc exp show I see a table with multiple rows, each corresponding to an experimental commit based off the HEAD commit. However, I also see a "workspace" row which includes information from HEAD itself. Since this does not correspond to an experiment, I'm wondering if there is a way to use dvc exp show but exclude this workspace row? The options in the dvc documentation seem to only exclude based on columns.
