Need help bulk adding hub pages

I know there are bulk page creation plugins but I need one beyond that. I have an automatic hub creation tool built into page creation page. With this tool it creates 5 sub pages with separate templates for every canonical page I create. For example I create page Test 1, it also creates 5 sub pages named test 2, test 3, test 4 and test 5, each based on a separate template. My problem is I have to create roughly 14,000 (not a typo) canonical pages each with a 5 sub page set. No plug in I can find supports this setup. I can create the 14,000 pages from a list of names I have already but it will not create the subsets. Any suggestions would be greatly appreciated. maybe even a macro that can be trained to select a name from a file list, insert it into the page and click create, (lather, rinse, repeat) 14,000 times.
