Can someone please help me on this?

Everytime when I refresh my pivot table with new information, the field
dropdown list will automatically select the new field created due to the new
information. Is there any way I can prevent excel from selecting the new
field automatically? I want to keep the current format with only the fields
I have previously selected, but once I refresh the data, the pivot table will
also include new fields from the new data.

Please help!

Thank you in advance!
