Can Balance Feeds be added to child of base element Balance Definition using HDL template?

Summary:

We used the base element name as the BalanceCode when submitting the BalanceFeed template. The template was successful and loaded the balance feeds. However, we don't want to load them to the base element balance definition. Instead, we want to load them to a different balance definition tied to the base element. But, we received an error message when attempting to use the template for this purpose. Screenshots are attached. Do you know if what we want to do is possible with this template? We have 118 balance feeds to add and we're trying to save time on doing this
