How do I stop Apple (OSX) Mail automatically adding me email signature to replies?

Thanks John.

Apologies - embarrassingly I missed the key-word out of the first line! It should read:

Other email clients (e.g. Outlook and Thunderbird) have an option to uncheck "automatically include email signature in replies". I can't find this option in Apple/Mac Mail (OSX 10.13 High Sierra) Appreciate that I can choose whether or not to include reply on each email but would be much faster to has this done automatically.

Is there such an option in Apple Mail? If not, is there a plug-in that adds it?

I.e. Other email programmes automatically include the signature on your first message but don't bother needlessly adding them on subsequent messages in the chain. Can Apple Mail do this?

Cheers
