Can I add dummy rows to a crosstab query in Access? [on hold]

Is it possible to add dummy row headings to a crosstab query in MS Access when the data doesn't exist in the source table/query? I'd like to indicate that I'm aware that a category exists, even though nothing currently falls under that category.

To illustrate, I'd like to take this output...

| Category    | Total  | Class 1 | Class 2   | Class 3  | Class 4  |
| PARTK2130   |  0.10  | 0.00    |  0.00     |  0.10    | 0.00     |
| PARTK3140   |  0.29  | 0.01    |  0.24     |  0.04    | 0.00     |
| PARTK4150   | 30.98  | 0.33    | 12.22     | 18.44    | 0.00     |

And make it look like this (notice the * New * rows)...

| Category    | Total | Class 1  | Class 2   | Class 3  | Class 4  |
| PARTK1120   |  0.00 |  0.00    |  0.00     |  0.00    | 0.00     | *New*
| PARTK2130   |  0.10 |  0.00    |  0.00     |  0.10    | 0.00     |
| PARTK3140   |  0.29 |  0.01    |  0.24     |  0.04    | 0.00     |
| PARTK4150   | 30.98 |  0.33    | 12.22     | 18.44    | 0.00     |
| PARTK5160   |  0.00 |  0.00    |  0.00     |  0.00    | 0.00     | *New*
| PARTK6170   |  0.00 |  0.00    |  0.00     |  0.00    | 0.00     | *New*
| PARTK7180   |  0.00 |  0.00    |  0.00     |  0.00    | 0.00     | *New*

The only way that I can think of doing this is by creating a new dummy source-table/query, populate it with some dummy records, then modifying my crosstab query as a UNION query that looks at this dummy source along with the original. I got it to work, but this seems like a like a lot of monkey business.

Indeed, I learned how to add extra columns when there is no data (see the Class 4 column and this post), so I would think there's a trick to add extra rows too. Hoping anyway.

Here's the SQL (Access SQL dialect):

TRANSFORM Format(Nz(Sum(qryPartK.MILES_OF_PHYS_LENGTH),0),"Fixed") 
AS SumOfMILES_OF_PHYS_LENGTH
SELECT IIf([PCT_SMYS]<=30,"PARTK2130",
IIf([PCT_SMYS]<=40,"PARTK3140", IIf([PCT_SMYS]<=50,"PARTK4150",
IIf([PCT_SMYS]<=60,"PARTK5160",IIf([PCT_SMYS]<=72,"PARTK6170",
IIf([PCT_SMYS]>72 And [PCT_SMYS]>=80,"PARTK7180",
IIf([PCT_SMYS]>80,"PARTK80MORE"))))))) AS Category, 
Sum(qryPartK.MILES_OF_PHYS_LENGTH) AS Total
FROM qryPartK
GROUP BY IIf([PCT_SMYS]<=30,"PARTK2130",
IIf([PCT_SMYS]<=40,"PARTK3140",IIf([PCT_SMYS]<=50,"PARTK4150",
IIf([PCT_SMYS]<=60,"PARTK5160",IIf([PCT_SMYS]<=72,"PARTK6170",
IIf([PCT_SMYS]>72 And [PCT_SMYS]>=80,"PARTK7180",
IIf([PCT_SMYS]>80,"PARTK80MORE")))))))
PIVOT qryPartK.CLASS_LOC_text In ("Class 1","Class 2","Class 3","Class 4");
