How to disable the OLE attachment button while still supporting OLE


Is there a way to disable the OLE attachment button on the Media Object toolbar while still allowing access to existing OLE attachments?

We are interested in migrating our OLE objects to file/URL objects but we aren't ready to do the conversion. We are interested in taking away the ability for users to add new OLE attachments and pushing them towards using file attachments while still allowing them to view existing OLE attachments. The ActiveX control seems to affect both the OLE attachment button and the ability to access existing OLE objects. I haven't found anything about controlling the buttons on the toolbar.

Thank you,
