Looking at the datasheet of this component, can you group together pins by their functions? for example for Power, 3v3, gnd_1 gnd_2 etc
Also can you place them into their respective sections based on their functions
NOTE: If you group them, can you not add the same pin if you already added them in a group? You should know which pin function is common for its function

I’ll update the nRF52840 symbol organization by assigning each pin to one functional section and one pin group only, using the datasheet pin functions as the source of truth. I’ll first inspect the current pins/properties, then apply grouped sections and verify there are no duplicate group assignments.

Done — I grouped all 49 nRF52840-QFAA terminals into mutually exclusive functional sections and updated Section, Pin Group, Pin Type, and Pin Description properties. I also created the detailed reference file here: nRF52840-QFAA-F-R Pin Grouping.
No pin was assigned to more than one functional section; multifunction pins keep their alternate functions in the descriptions.
