Background Task Progress bar with new add_rows method

Is it possible to build some progressbar with the new add_rows function?
Previously adding rows was a loop with a single row add_row and it wasn’t hard to add some integer.
Is there a way to do it with a new add_rows method?

app_tables.assay_databank.add_rows(dict_items)

No, I don’t think there is, but I’m moving this to Feature Requests.
