Are we able to add help text for the esignature?

Summary:

We are a global company based in the US. The e-signature is only accepted in the format "FirstName LastName".

However many of our global sites a signature is "SurName GivenName" (or "LastName FirstName") and a lot of candidates in those countries reach out that their signature has not worked, as it may not be common knowledge to flip the signature.

This is happening on both the application and the offer.

The only thing I've found is the e-signature statement in Recruiting Content Library, but we don't want to add help/descriptive text to that.

Is there any other way to add help or descriptive text for the e-signature?
