For organizers who already have a fixed conference program. Import the schedule, choose the presentation for each session and export original PDF/PPTX files with room instructions. Save each issued handoff so a later replacement does not change the earlier one.

A practical example

Twelve talks, two rooms, one reviewed handoff

Start with

Cedar Forum is an original fictional program across two rooms and two dates, with received file versions and one session that deliberately has no presentation file.

Get this result

Each room receives staff instructions linked to the exact selected original files. A replacement appears in the later issue while the first issue retains its earlier file.

Examples use fictional or synthetic data. Follow this example step by step.
