Is it possible to resynchronize after effects source name with its corresponding photoshop layer name after renaming the source name in after effects?

I have an after effects project and a script that exports the after effects animations for use in Unity3D. The animation is complex and uses over 100 layers. Those layers are imported from a psd file created with photoshop. The layers in after effects and the psd correspond 1 to 1.

The layers from the psd are exported as individual png images. The layer names need to be unique, and the same as the source name in after effects as that is what the export script uses to identify which image is where.

When you import layers from a psd into after effects, it is possible to rename the layers in the psd and after effects source name gets updated automatically. That is until the source name gets renamed in after effects.

Due to a communication mishap, the source names in after effects were all renamed. It is also not desirable to use the backups as that would result in almost a week of lost work.

Some of the psd layer names need to be changed (several of them).

Is it possible to synchronize the names again (psd layer -> after effects source name)?
