It would be nice to have own strings for "Reject all", "Decline all" etc. Then again this is quite repetitive.
Maybe there should be a specialized "all" string and a quideline how to to combine it with the words above.

Something like this perhaps:

```php
$reject = elgg_echo('reject'); // "Reject"
$reject_all = elgg_echo('action:all', array($reject)); // "%s all"
echo $reject_all; // Prints out: "Reject all"
```
I'm not sure how this would work with different languages. At least with English and Finnish this would be fine.
