Make iProcurement Attachments Readonly

My users are being moved to store attachments in Perceptive Software.  I use API's to generate web links to Perceptive.  I've been able to personalize iExpenses to turn attachments to readonly on the Controller with this code:

	public void processRequest(OAPageContext pageContext, OAWebBean webBean)
	{
	super.processRequest(pageContext, webBean);
	OAMessageAttachmentLinkBean owb = (OAMessageAttachmentLinkBean)webBean.findIndexedChildRecursive("ReviewGenInfoHeaderAttachments");
	AttachmentsUtility.configureAttachmentCapabilities(pageContext, "OIE_HEADER_ATTACHMENTS", owb, Boolean.FALSE, Boolean.FALSE, Boolean.FALSE);
	}

Is there a similar bean in iProcurement that can be used to make attachments read only?

Thanks.
