SPIP feature request to prevent duplicated ARTICLE LOGO

While writing article or editing, it is possible to choose pictures
from media library, but not when you want to set ARTICLE LOGO. If you
have already a picture uploaded, and you want to re-use, then you must
upload it again. That makes IMG folder unnecessarily larger than it
should be.
I don’t know about other webmasters in SPIP community, but in my case,
I have hundreds of duplicated ARTICLE LOGOs.
I don’t know where I should ask core developers to add media library
select for ARTICLE LOGO.
I ask it here first, maybe the other webmasters have faced the same,
and want to have this feature included.
