Task scheduler and additional page sizes

We are trying to add one more page size to the Task Scheduler printing options, specifically, a size that can accommodate more columns than Tabloid or A3. It appears there are some files in “…WEB-INF\print\scripts” which define the pageSize options. However, adding a new pageSize or tweaking the existing “widthInInches” parameters do not seem to have any impact. It appears that these scripts may already be compiled so our changes are not reflected.

Has anyone discovered a way to add/modify the page sizes in Task Scheduler? As Puppeteer supports various tweaks to the pageSize, what is the best way to customize the default options in UX? Thanks!
