Yes. You can undo a plan whose status is Run finished or Partial. Open the plan and click Undo plan changes.
Undo puts back the product fields the plan changed, in SureDone only, and ends the listings the plan submitted. It doesn't relist anything, doesn't remove categories or item specifics Taska filled in, and doesn't return credits.
Undo ends every listing the plan submitted, including listings that were already live before the plan ran. To remove one listing or fix one field, it's usually simpler to change that product directly.
Read "Undoing a Listing Plan in Taska" before you use it.
