Question : SQL criteria applied to nested queries

I have a report that uses a query as the record souce.  The query used in the report contains 3 nested queries that perform separate calculations.  I call the report from a parameter FORM using the following code:
    If ViewType = myPRINT Then
        DoCmd.OpenReport ReportName, acViewNormal, , SelectionSQL, , ReportType
    Else
        DoCmd.OpenReport ReportName, acViewPreview, , SelectionSQL, , ReportType
        DoCmd.RunCommand acCmdFitToWindow
    End If

The SelectionSQL is generated from the data entered on a Form (up to 30 different selection ranges).  This method works on single layer queries, but with a multiple level query the SelectionSQL is not applied to the nested queries (selects all records).  How can I make the nested queries utilize the SelectionSQL?

I tried changing the SQL of the query using something like:
       Set CurrDb = CurrentDb()
        WhereStmt = " WHERE (" & SelectionSQL & ");"
        CurrentDb.QueryDefs("QryRTypeRateDetail").SQL = _
            Replace(CurrentDb.QueryDefs("QryRTypeRateDetail").SQL, ";", WhereStmt)
        Set CurrDb = Nothing

This just appends the WHERE statement to the query after replacing the terminating ";" character.  The problem is the second iteration requires different logic to filter out the old WHERE statement and replace with a new WHERE statement.  I can probably figure out how to write this code, but the process is VERY messy.

Is there a clean way to set a filter on a query without changing the entire SQL?
I tried things like:
        CurrentDb.QueryDefs("QryRTypeRateDetail").Properties("Filter") = SelectionSQL
        CurrentDb.QueryDefs("QryRTypeRateDetail").Properties![Filter] = SelectionSQL
But they all give syntax errors.  Couldn't figure out how to set the filter property on my query.

Any help anyone can give me would be greatly appreciated.  I am in a big rush for this.
