Good afternoon. There is currently no such functionality. Edit to:
1. if a product with the same name exists in the system, which is recorded in the additional field
http://joxi.ru/MAjEDnoFkdGP32, a new product with the same name was not created - 1h
2. the task did not go to this stage - give an error 1h
3. after switching to this stage, it was automatically transferred to the specified status - switch to another status - 1h
I like option 1 the most, which one will be more convenient for you - choose.
