I think that this already exists, in a way: Look at the documentation 
for CellTags. It of course does not work exactly how you described, but 
it basically should allow you to do what you want:

1) Give the cells you are interested a cell tag, e.g. closable_cells 
with "Cell" -> "Cell Tags" -> "Add/Remove Cell Tags".

2) Then use "Cell" -> "Cell Tags" -> "Find Tags" to select all cells 
with a given tag.
