Add Yarle template feature

[boardtc]

Has it been considered to expose the template feature of the Yarle importer? I am importing Evernote .enex files and I like that feature.

Using Yarle the default template has a few options (only the first 2 get filled for me)

{created-at-block}Created at: {created-at}.{end-created-at-block} {source-url-block}Source URL: .{end-source-url-block}

which results in

Created at: 2020-11-19._ Last updated at: 2020-11-19._

These are nice options I think after an import. Can this template feature be added to the importer interface?
