I am far from an expert in this area so excuse me if I do not use the correct terminology.
I want to create an RSS feed containing nodes that do not get updated directly. They use D3.js javascript scripts that references files which are used to create the charts. I update the files daily by uploading them to the host. I store the new file names in blocks which are included in the relevant nodes.
Is this possible? Do I need to update the Updated date and if so is there a way to do this without editing each node?
