How to configure and enable pulldown resistor in the GPIO pins of Kinetis DSC?

I understand Kinetis family of MCU/DSC have a Portx_PCR register for configuring and enabling pulldown or pullup resistors.

 

However this does not appear to be available in the configuration of the component (at least if one is interested in an individual bit I/O pin) be it in the High Level BitIO component or the logical LDD bit IO one, not even in Advanced mode.

 

Is there a means of achieving this via PE software or the only recourse is to write to the register in the main routine after the call to PE_low_level_init()?

 

Thanks in advance,
