Each template is used in different scenarios. It should be very apparent which ones for most of them (e.g. Rich Text Editor Media is of course used when inserting media in the Rich Text Editor).

Furthermore, should there be a need for a more advanced use case, which is not covered by the standard Stampvalues, then the pipeline GetAssetFieldValue can be extended to understand custom Stampvalues.
