Where can I find the filaments' tracking information (done by AAFDC code)?

I am looking for filaments’ tracking information. Each detected filament is linked to its previous (next) appearance in the image captured before (after). So, each filament should have “follows” and “followed by” information.

I see this on LMSAL website. E.g.:

But HEK module in SunPy does not seem to have such pieces of information. How can I use SunPy API to get such information?
