System: Win NT4 SP 6 and Outlook 98 ver. 8.5.5603.0

I have a process in which a custom form contains a customaction that invokes a copy of the current custom form, addresses it to another recipient, and sends it immediately.
My problem lies in that the custom form has 2 attachments that need to be attached to the new form from the customaction. Is there a way to do this (i.e attach an attachment)?
Thanks in advance.
