Is There a DELETE Endpoint for Programmatic Cleanup of API-Generated Presentations?

Hi Max-After several months of operation, my "API generated" workspace tab has accumulated hundreds of presentations that serve no purpose. I have no way to clean these up programmatically, forcing manual deletion through the web UI. Is there a another method I am missing? Any talk of adding a DELETE /v1.0/gammas/{gammaId} endpoint to allow programmatic cleanup of API-generated presentations? Thanks and Happy New Year!
