A lot of us don't have multiple TMs who can jump into opu. Having the option is one thing, but forcing multiple batches that all have to be done in 30min could cause more issues than it would solve. If someone is the only person on hand who works orders, they will have to run around twice as much just to finish the same amount of items as before.
Couldnt we just institute a "split batch" option for larger orders instead? Let different store formats with more or less fulfillment TMs do what works for them best.
