Allow custom email x-headers defined per label
Allow custom email x-headers to be defined per label to allow compliance with various country email labelling standards for government.
This is available in the Unified Labeling client as described here: https://docs.microsoft.com/en-us/azure/information-protection/rms-client/clientv2-admin-guide-customizations#apply-a-custom-property-when-a-label-is-applied
Does this allow token injection into the custom header? IE. Can I format a header with some fixed text and inject a dynamic token like the user email address?
Microsoft needs to do this asap.

This would be extremely helpful and prevent the requirement for trying to manipulate msip_label x-header to try and comply with the official standards. Getting rid of third party software that solely exists to inject this metadata would be great and ****** support within Office web apps is the final tick. This limitation would be preventing a lot of federal organisations from truly adopting Office 365 cloud services.
You can view the full ********** government standard for email protective marking here: https://www.finance.gov.au/files/2012/04/EPMS2012.3.pdf
From what I can tell, the subject line manipulation is not mandatory, but would be beneficial. Possible transport rules could help here anyway. The header though is critical.
The Australian government standard has following format:
X-Protective-Marking: VER=2012.3, NS=gov.au, SEC=UNCLASSIFIED, ORIGINemail@example.com
Where "SEC=UNCLASSIFIED" will differ based on the label, and "ORIGIN=…" is the email address of the person that applied the label.
