You don’t have to list them one by one, you add the products to a batch and then upload the batch. Since you have to select a default category for each batch, I’d recommend sticking with with products in the same category for each batch.
The one drawback with Doba is that it’s not your specific inventory list, it’s all Doba inventory. But you can do a search by category, select multiple products you want and bulk add them to a batch.
