Mogrts are great in many ways, but still limited in others. Providing overlays for an end user - for social safe zones, for example, or as additional instructions for proper template use or timing - can be very helpful, but requires an additional control they'd need to disable before exporting.
Might it be possible to enable Guide Layers to pass through to Premiere, such that they'd be visible to the Premiere user, but would NOT appear in exports?
