Pasting over lists

[alehandrof]

When moving list items around I often find myself pasting a bulleted line on a line with a bullet created by Smart List. So, if I have - Something on the clipboard I end up with:

- - Something

How possible/efficient/practical/etc. would it be, when pasting in markup.list, to examine the clipboard and, if the content begins with the same bullet as the current line, to paste over it? (This would probably work by removing the - that the Smart List has created, rather than fiddling with the content in the clipboard.)
