Custom blocks drop down menu.

I am currently using autocad lt 2000, and I am trying to make the switch to DS. In autocad I have a Blocks drop down menu that I use for various drawings. For the custom menu items my command string goes something like this.......^C^C-INSERT METER1

In autocad when I do this it inserts the METER1.dwg block, and I place it where it is needed. I used the same command in DS. When I select my block from the drop down menu it asks me to specify block name in the command window. How do I specify the block name in my custom menu command string?
