Sort order "by name" in partner dropdowns

It looks like the partner dropdowns in "Send file to partner" and "Create communication datasheet" are not sorted or maybe sorted by an internal ID.
This is not helpful if you have to deal with about 50 or more partners.

So I would like to suggest to have a sort order "by name" in these partner dropdowns ... and others as well, if there are more.

(The partner dropdown in the filter area and the list of partners in window "partner configuration" are already sorted by name, I think.)
