Currently we can set "dynamic node selection" on policies.
It would be really nice to have this same functionality on both Reporting, and Rules.
In Addition or alternatively, Allow for Nested Policies, Where you can nest a dynamic selection policy within another policy:
Example:
Rule A applies to dynamic node XYZ in Policy A which applies to all nodes with custom property "123" Policy B in Report X
Rule B applies to dynamic node ABC ALSO in Policy A which applies to all nodes with custom property "345" Policy C in Report X
