From 2021 FD website read the rules and submit as directed:
Q: How does my club submit an aggregate club score? Does the club need to add up each participating member’s scores and submit a club entry with the aggregate score under the club call sign?
A: Each participant will submit his or her own independent entry under his or her call sign. 2021 FD will calculate the aggregate score based upon the club name entered on the official Field Day entry form via the web applet (preferred method) or on the paper Field Day entry form. In order for results to be tabulated correctly, all club participants must enter the club’s official name exactly the same (see below), avoiding abbreviations or acronyms. This is important!
