Is there any way to enforce padding between subroutines using the scatter file?

Hi!

I am using an ARM Cortex-M23 microcontroller. I wish to pad every subroutine with certain number of bytes. Using the ALIGNALL attribute on an execution region I am able to achieve some success but I cannot control the number of bytes. Further, the ALIGNALL attribute does not seem to work on veneer code. While I can place the veneer code in a separate execution region, I cannot align the veneer code as I please. Is there any way to achieve what I am trying to do?

Thank you
