Suggesting specific Parents and not just object types possible?

Hi Everyone,
It would be a great quality of life change to be able to not only set hints for object types, but also to have specific suggestion of entries as parents. E.g. If I set a specfic experimental step for a scanning electron microscope it would be nice to have the availaible microscopes as suggestions in the Parents section.
Is that already possible if yes, how?

Thank you
