Easiest way to find ThinkPad Part Numbers/FRUs?

[Big McLargeHuge]

I know I can just google "T490 PSREF" to get the spec sheet with all the possible hardware configurations, is there a similarly convenient way to get all the part numbers/FRUs for said parts without having to laboriously hunt for them on a case-by-case basis? My dream would be FRUs with this addition right beside the parts specifications but sadly I don't think that exists.

Up until the xx20 Series (from 2012), the part- or FRU-numbers were listed in the HMM-manual.
From xx30 Series onwards, these numbers are listed in a separate (.pdf or .xlsx) file.
These have different names, such as
T430s_fru_bom_20130401.pdf
T450_frubom_20150127.pdf
T480_frubom-20L6_2019-01-20-13-08-52.xlsx
T14_gen3-PartsExport_Model-21ah0018us_2022-09-09-06-26-54.xlsx
etc.

Search Google/DuckDuckGo/etc. for 'lenovo xxxx parts list' or 'lenovo xxxx frubom' etc.
