wdx_exif Plugin: how to change the "default" formats?

[Darwin4Ever]

Hi,

When the "wdx_exif Plugin" is used in the MultiRenameTool
I would like to change the "default" formats in use (without having to select every time the format I need) as an example for :
[=exif.DateOriginal]
[=exif.DateDigitized]
[=exif.TimeOriginal]
[=exif.TimeDigitized]
In general it might be useful to know how any default can be modified in the "wdx_exif Plugin" or one of the available formats been set as "default"

Thanks
