Merge existing pdfs from api call to newly generated pdf

[candy-man]

Is there a way i can send an already generated pdf via post call to jsreport where jsreport can generate a new pdf and merge it with the one that was sent via api?

My backend is in dotnet and i'm calling RenderByNameAsync() method

Check out this example
https://playground.jsreport.net/w/anon/hKXuHP1E

const jsreport = require('jsreport-proxy')
async function afterRender (req, res) {
    res.content = await jsreport.pdfUtils.merge(res.content, Buffer.from(req.data.externalPdfBase64, 'base64'))    
}
