I don’t have much hope that such a feature will appear given how long these requests have been coming in, although I would love for it to exist.
I’m not sure who from the original engineering team is actually working on Desmos Classroom since the split, but I get the impression that the more regular improvements will be made to the Graphing Calculator, while the Amplify crew are more interested in making curriculum than improving the tools.
One piece of evidence is the drying up of this list: New Classroom Features (Ongoing) and another is the fact that feature requests like the above, or even the ability to search reliably for activities, have not been implemented.
