[O] expand view for all items in sparse tree

[robin]

hello 

does anyone know if there is a possibility to expand all items including list
items in a sparse tree for a certain tag to export only the visible to eg latex?

my steps are:
- C-c / :MYTAG
now all headlines with the tag are shown. That's fine. But now I can only cycle
the visibility of one of the sparse tree's branches and not all of them so I get
something like
* Item :MYTAG
  - [X] do this
  - [ ] do that
* Item2 :MYTAG
 (hidden -[ ] do this as well) <--- but I would like to export this as well...

any shortcuts I have missed so far?

best regards
