So I have a custom image for example, a sick design and in the centre of it there's some text that I want to be, for a website, a user's username. My plan was to use Affinity designer to make the design and put the text in, make the text something like "USERNAME", and use a script on my web server to replace "USERNAME" to the actual username, then either render in Inkscape (which you can automate because of the command line) or just get the web browser to show it. I cannot currently do this with Affinity because the text element is not one clear element, but split into many different elements meaning I can't make a script look for "USERNAME" and replace it.
