When Adding Custom Field, Need to be Able to Rearrange/Reorder

When Adding Custom Field, Need to be Able to Rearrange/Reorder

It doesn't appear possible to reorder the fields under settings, even if I add a custom field.    So, the flow of input is greatly affected in the new field should be third from the top but by default it's added to the bottom.
 
If there's a way to correct this now, please let me know.  If not, can this be added to the Roadmap.
