Control for subgrid with child items

Hi there, would it be possible to have a subgrid component that has child items

Is it possible to have a sub grid that also shows child items for record, where both the record and its child items share the same parent/lookup?

An example:

Table Relationships:

• Course 1:n Enrollment
• Student 1:n Enrollment
• Student 1:n Checks

On a form for Course, there would be a subgrid of Enrolments, with Checks as child items (noting that Enrolments and Checks both have a lookup to the same Student, so the child items should only show the Checks for the Student for that Enrolment)
