I have never heard of adding a second Attachments column, and I don't think you can.

I would suggest using a naming convention to either prefix or suffix the file names so you can tell which work order they belong to.

Something like

    1_some file name.jpg
    1_some other file.jpg
    2_second work order file.jpg
    2_another file.jpg

or

    some file name_1.jpg
    some other file_1.jpg
    second work order file_2.jpg
    another file_2.jpg

After seeing your code you posted in your comment, what I'm suggesting would be to edit what you have there, but do some string concatenation to put a prefix on the file name.  It could either be in the `Set` or in the `Collect`, the way you have it there.  You could either do

    Set(varJobImage, "1_" & GUID());

and leave the `Collect` as is, or leave the `Set` as is and change the `Collect` to be

    Collect(
        NewReportVehicleImageCollection,
        {
            DisplayName: "1_" & varJobImage & ".jpg",
            Id: "1_" & varJobImage & ".jpg",
            Value: Camera1.Photo
        }
    );

Then you'll know any attachments that start with "1_" are for the main work order.

Do the same with "2_" for the secondary work order.

Actually, I found [this article][1] that talks about different ways to concatenate strings in Power Apps, and given that using the `$` string interpolation syntax is possible, I think it would make your code much easier to read if you used that, and moved all of the string concatenation into the `Set`, and not do any of it in the `Collect`:

    Set(varJobImage, $"1_{GUID()}.jpg");
    Collect(
        NewReportVehicleImageCollection,
        {
            DisplayName: varJobImage,
            Id: varJobImage,
            Value: Camera1.Photo
        }
    );
    
Nice and clean and easy to see what's going on. :)
