Multiple EAs using same text

Hello,

I am currently involved in a project that consolidates multiple documents into a single, large PDF file.

Each original document within this PDF includes the text "CL-SIG," which indicates where a signature box should be placed.

For example, we might have 50 smaller PDFs that we have combined into one large PDF. This results in 50 instances of the "CL-SIG" text throughout the document.

I need to insert a signature block at each of these 50 locations, whilst also ensuring that signing one block applies the signature to all of them.

A challenge we face is the variable number of PDFs involved, ranging from a minimum of 2 to a maximum of 100, as defined by the project scope.

Is there a straightforward way to accomplish this using the ApexSDK?

The example below is how we currently attach a single signature block

// Signature Block/Approvals
OneSpanAPIObjects.ExtractAnchor signatureEa = new OneSpanAPIObjects.ExtractAnchor();
signatureEa.text = 'CL-SIG';
signatureEa.index = 0;
signatureEa.width = 100;
signatureEa.height = 50;
signatureEa.anchorPoint = OneSpanAPIObjects.AnchorPoint.TOPLEFT;
signatureEa.characterIndex = 0;
signatureEa.leftOffset = 0;
signatureEa.topOffset = 0;

OneSpanAPIObjects.Field signature = new OneSpanAPIObjects.Field();
signature.type = 'SIGNATURE';
signature.subtype = 'CAPTURE';
signature.extractAnchor = signatureEa;
signature.name = 'Signature';
signature.width = 100;
signature.height = 50;
approval.fields.add(signature);
