Can I use variables in the header section of the text exporter? I know that I can use some general variables such as today's date but what about other variables that are associated with with particular photos? I haven't actually tried it but I assuming that if I try to use a variable such as capture date it will fail because the software won't know which photo to look at. But in my case the capture date will be common to all photos in the contact sheet. But I realize that this is a special case that won't necessarily be true for all users.
Is there any way to make this work?
