Master content, custom content

Hi!

I am creating Storyline templates very often, that are later reused by my colleagues.
It would be a great help if I could highlight, which objects should they customize, and which ones should remain as they are.

Currently I can lock or unlock content if I want to make them editable, or keep them safe. Sometimes I put the very sensitive objects, JavaScripts on the Slide / Feedback Master to make them less accessible for unexperienced colleagues. But it would be really a great feature, if I could somehow highlight them which objects they could and should customize.

Thank you in advance,
