Hey @cedric.devos,
So what you’re actually looking for, is to restrict the options shown in this section right?
currently not possible but have heard it before, and it is listed as a feature request.
PS sort of a workaround, but you could add an additional check that forces an Annual Account template into being unreconciled.
This will cause the workflow becoming different from 100%, and as most users will known, you cannot download a XBRL file if your workflow isn’t finished yet.
A similar case was described here:
Perhaps too big of a workaround, but hope it helps you though (you’ll need to do some tweaking to teh code obviously, and link it to the check of the WCO template)
