Getting moved files to inherit permissions in Linux

I have set up a folder that is assigned to a group.

drwxrws---+   2 operator    IDGroup    4096 Jul 21 10:22 MyTest

The following ACL is applied:

setfacl -Rdm group:IDGroup:rw MyTest

Files created in this directory inherit group IDGroup which is correct.

Files moved into this directory retain their original group ownership which is what I do not want.

Is there a way to have files moved into this directory get reassigned to group IDGroup?
