Any way to join separated tumblr reblogs into one file?

[nameisafunnyname]

Heyo, I'm using TumblThree to archive my liked posts on tumblr. It's downloading everything, but it seems like whenever there's a reblog or an anon ask, the program separates those into two files, and because the IDs are different I see no obvious way to join them together.

My final goal is to perhaps create some sort of offline viewer, so I'd love to get it working right. Thanks, have a good one :)
