DRC Error Marker Limitation

Hi friends,

I have a problem on DRC error marker. After running DRC, let's say, it
was found that there are 2000 shapes violating rule A.

In the Error Layer Window, it shows:

Marker: 1 of 1000 <-- limited to 1000 (should be 1500)

[2000] Rule A | [1500] cell 1 <-- this one is selected
[500] cell 2
.......
.......

The problem is that the maximum number of markers shown is limited to
1000. If I have error markers more than 1000, the remaining markers
cannot be shown. How could I increase the maximum number of markers
shown?? Any AVparameter or function can do this??

Any guidance and comment is highly appreciated.

Best regards,
Will
