Review agent subtasks

[GoldenLeafBird]

When reviewing a lot of diffs, the review agent can get overwhelmed trying to understand all the diffs.
Could we have an option to let the review agent create subtasks so that it can work through the diffs one by one (or grouped per category?)?

I now sometimes find myself triggering the review by selecting review mode, then switching to Orchestrator to group the diffs by type/file and dish them out through subtasks.
