Possible to mark email to prevent accidental deletion?

Is it possible to mark, flag, or “park” an email in eM Client to prevent inadvertent deletion?  In some other mailers this is possible (and very useful).  Such a feature means that a manually-parked email must be manually un-parked before deletion is allowed.

This is much different than a simplistic feature where the app asks you to confirm each & every deletion.

I checked the menu settings and the forum archives and didn’t see anything on this topic.

Thanks in advance.
