is there a way we can set subtotal for numeric fields only ? or any 1 or 2 fields rather than all ?
Thank you for your question. Currently, such feature is not available. Please let me know if you have other questions.
Whether we can edit the source code after purchasing the service to realize the customize setting for the specific field
