# Can multiple script supervisors line the same script?

**Yes — multiple script supervisors can collaborate on Lining**, but there's an important constraint to plan around: when you [import](https://help.scriptation.com/en/article/how-do-i-import-shared-lining-layers-17fuoon/) a shared Lining Layer, it only applies to scenes that **don't already have lining** in the target script.

|| 📝 NOTE: Lining Tools is an [Industry Pro](https://help.scriptation.com/en/article/what-is-scriptation-industry-pro-1jfjecg/) feature.

### The constraint

Imported Lining doesn't merge with existing Lining on the same scene. If you attempt to [import a collaborator's `.slf` file](https://help.scriptation.com/en/article/how-do-i-import-shared-lining-layers-17fuoon/) into a script that already has tramlines on the same scenes, the import will fail.

This is by design: Lining Layers are scene-scoped, and Scriptation can't safely merge two supervisors' tramlines on the same scene without losing information.

### The recommended workflow: divide scenes by supervisor

If multiple script supervisors are covering a show, **divide the scenes between them upfront**. For example:

* Supervisor A takes scenes 1, 3, 5, 7;
* Supervisor B takes scenes 2, 4, 6, 8.

Each supervisor lines only their assigned scenes. At the end of the day, they [share their Lining](https://help.scriptation.com/en/article/how-do-i-use-share-lining-a9hufh/) with each other (or with the editor). On import, each script ends up with the full set of tramlines because there's no overlap.

| ✅ TIP: Decide who covers which scenes before the shoot starts. Splitting on the fly is harder once tramlines exist on both sides.

### When the same scene needs lining from two supervisors

Occasionally a scene needs coverage notes from a second supervisor — for example, if the lead supervisor missed a setup, or if a re-shoot adds a different angle. Because you can't import overlapping Lining, the workaround is to send those additional tramlines through **Editor Export** as additional pages.

1. The second supervisor lines the contested scene in their own copy of the script;
2. They run an [Editor Export](https://help.scriptation.com/en/article/how-do-i-export-my-lining-ie-to-an-editor-lbt324/) for just that scene;
3. The resulting PDF is shared as an additional page (or attached to the main Editor Export) for post-production.

The editor sees both sets of tramlines — the original supervisor's via the main Editor Export, and the second supervisor's via the additional page.

| ✅ TIP: If you're frequently running into this, it's a sign the scene assignment needs to be revisited mid-shoot. Re-split scenes between supervisors as needed.
