Periodic updating in bulk of e-shop availability from a custom field

As we mention here, there is the possibility of sending items in bulk to an e-shop.

Instead of sending the availability field we can choose a custom field.

1. We copy the base and call it null. Choose so that it is on the right side
2. We write the link that the availability is sent to the e-shop
3. Fill in the custom field number you want with the letter “t”
