Phoenix Roadmap: Span/Trace Annotations for Dataset Creation Inquiry

Was wondering if span or trace annotation for dataset creation and/or evaluation is on Phoenix roadmap at all? We are already using phoenix for a lot of the heavy lifting with tracing and visualizing traces however we are still exporting these traces out and manually converting them into datasets for eval/examples optimizations/etc What would be awesome is if there was a way for me too add manual annotations , rewrite expected output, etc when reviewing a span (see screenshot below) Current plan is to load phoenix traces offline and annotate via doccano PS is this available in managed arize?
