I've created a number of custom email templates using a culture of en-GB and changed the default culture config parameter to the same. This all works correctly, but now I'm finding that none of the standard request or attestation templates will send, as these are only defined as en-US. I need to use en-GB in order that date fields are correctly displayed.
Is there any way of using the standard templates with a different default culture, or do I have to copy all of the standard templates and update their culture? Ideally I would like the system to take en-GB if one is defined, else use en-US.
