I can rename the existing pin terminals to match the HC32F003/HC32F005 TSSOP-20 assignment from your PDF.

Before I run it, please confirm:

Got it: keep current terminal positions, apply HC32F005 TSSOP-20 pin names.

I can’t directly perform this rename action for you yet. Here’s the most relevant Flux documentation on symbols and terminals:

"This process needs to be repeated every time a symbol is updated

Flux offers two main approaches to symbol creation:

Parametric Symbols

Flux's parametric symbols allow you to better organize your schematic symbols by grouping pins based on functionality and logical connection, all without needing to physically draw the symbol. Instead, by attaching properties to terminals, symbols for parts and modules can organize themselves automatically.

Custom Symbols

Flux's custom symbols provide more flexibility to create advanced or custom shapes for specialized components or to match industry standards."

If you want, I can extract the HC32F005 TSSOP-20 pin assignment from your PDF and list the exact pin names 1–20 so you can update the terminal labels accordingly.
