Document modification in AII?

Hi all,

I would like to modify a document in AII. Is it possible to do so? If so how is it done.

I do not find any provisions available in AII UI to modify the document contents .

Can it be done in AII UI or is there some other way?

For instance, consider a document which has observed ten items.Now if i would like to modify the document by deleting the last two observed items,how should i go about doing that? is there a way to do that in AII?

Help would be very well appreciated.

Thanks in advance,

Vivek
