How to distribute ECTR config files needed before logon?

Hello experts,

I've read the blog entry explaining the backend configuration:
https://wiki.scn.sap.com/wiki/x/ZDOvH

Under "3 - Boundary Conditions" it is noted that the backend config cannot be used for files needed before logon. However, also these files need to be distributed during installation and in case of changes. As PLM_INSTDIR is in the Programs (X64) directory per default, most users will not have write authorizations there.

Is there a proper way to achieve distribution of plm_initialize.bat, saplogon.txt and others?

Thanks in advance for your replies.
