I am able to successfully knit Powerpoint slides from R Markdown using a custom template.
I want to add a custom 'footer' to each slide. This is present in the template. I do not know how to add this content using R Markdown.
The default template includes a footer, but the support page does not provide information about how to customise the text that goes in that footer from R Markdown (https://support.rstudio.com/hc/en-us/articles/360004672913-Rendering-PowerPoint-presentations-with-RStudio).
How do I add a custom footer to a Powerpoint slide in R Markdown?
