Change MS Access report.openargs to allow a user defined type in addition to a string

In an Access application that I am currently working on, I would like to pass a class (user defined type) as a report.openargs argument. This would allow me to bypass a recordsource bound to a table or query and not have to hit the database for a source. Currently, Access allows only a string as an argument.

for example:

Dim myClass as clsMyClass
