Formatting date and time when renaming with {created} tag

I'm trying to replace some stuff in filenames. I have basically figured out exactly what I need, but it seems I cannot get dopus to cooperate on the final bit. Here's my regex:

old name: ([^-])(.)
new name: \1-{created|yyyyMMddHHmmss}

Unfortunately, it seems the {created} tag does not take time formatting and simply applies its own. Is there a way to get the result I want?
some_file_name-20190104155827
instead of:
some_file_name-2019-01-04 15;58;27

Example 10 shows one way to do it:

Thanks that did the trick!
