You just need to create a new package object with signers you want to replace the placeholders and other infos you want to replace from the template and call CreatePackageFromTemplate()function. The request payload is almost the same as above JSON.
If you create your template through WebUI, the only thing to locate the specific signer is the placeHolderName I believe. So if you can, still suggest to use SDK to create the template so that you can assign your placeholder ID already.
