The Avaya Site Administrator (ASA) software will let you do that.
If you can, go to the Avaya Support site and download ASA and the latest service pack. Install both. Note: This is a Windows only program.
In ASA go under Advanced and use Report. This will bring up a little window where you can type in a command or use the dropdown menu to select one.
It's in this window that you type the multiple commands. You can separate commands with semicolons: "display vector 1; display vector 2" (no quotes). Try two or three commands until you get it right.
You then have three options: Screen Capture to a printer, Export screen capture to file, or Export fields to file. Select "Export screen capture to file" to open up additional fields.
Enter the appropriate directory and file name and select "Append to existing file" so that each sequential command doesn't overwrite the previous.
One of the things I did way back when is list out all the commands I wanted to run in Notepad and get the format correct, then just copy-paste the whole thing into the Report command field. That was a lot easier than trying to type everything out in that tiny little space.
You can open your vector file in MS Excel to have a nice view, with line numbers in column A and Commands in Column B.
