Feature Request: Per-Column Output Slice Selection in Video Routing

I do not think this is possible yet, so here is a feature request.

Description:

Allow users to select a different Video Routing slice (output surface) per column rather than per layer only. This would enable dynamic changes in which part of a video is shown on a screen throughout the timeline - without duplicating video layers or increasing playback load.

Use Case:

A performance artist wants to display different cropped sections of a single 4K video on a vertical screen at various moments in the show. Each column represents a different cue or phase of the performance, requiring a different slice of the video. Instead of creating multiple heavy layers with identical media, the user simply wants to switch the routed slice per column.

Benefits:

• Greatly improved performance (especially with high-resolution media)
• Cleaner project structure (no need to duplicate layers)
• Easier programming and touring setup
• Aligns with Millumin’s per-column design philosophy
