How do I integrate SDIO or any other library in Simulink for STM32-MAT?

Is there an instruction on how to integrate ready-made libraries into a Simulink for STM32 MAT/TARGET as it is done for Arduino? For example, to work with an SD card using SDIO or SPI? There should be a way to work with the SDIO or SPI SD card without manually prescribing the initialization algorithm and the FAT management system. It is much easier to use a ready-made C / C ++ library for this. Can integration be done with the help of a Simulink S-function block? If so, is there an manual?

Do you know if you had any news about that ?
