Authorized Signatory for an Anonymous LLC

[Talo Tupou]

Hello my fellow investors. I'm in the process of creating 2 LLCs. One is a holding/Parent LLC (WY LLC). The 2nd is a Child LLC (FL LLC). I'll be using the FL LLC to do wholesale deals and flips and my WY LLC will be the owner/member managed of the FL LLC so my name doesn't show up on public record.

When I go to finish creating my FL LLC they ask for the Authorized Signatory. My problem is: the company I'm creating this LLC through, Zenbusiness- is saying that I can't use another LLC as the Authorized Signatory which makes sense that it has to be a person but again I don't want my name to be on there as this has to be made public according to Zenbusiness. 

So How do I get around this? Can I just use a registered agent this one time to open the LLC as the Authorized Signatory and then I just sign all the other paperwork/contracts as the President since I'm authorized to do so through my operating agreement?
