How to add a board supported in Ardunio but missing from PIO?

Hello

Support for the board I would like to use is now in the Arduino core:

(Release Arduino Core for STM32 2.11.0 · stm32duino/Arduino_Core_STM32 · GitHub)

variant(WL): add Oceanus-I module and EV

I need to work with this in PIO.

Is there a way I can do so?

Thanks
