Steps to reproduce:

1. Go to Zabbix
2. Select Monitoring
3. Select Latest Data
4. Enter a host group (not strictly necessary)
5. Select an application (not strictly necessary) – I used Filesystems
6. Enter a name (not strictly necessary) – I used "(percentage)"
7. Check some of the boxes (you could just use the check all box)
8. Click "Display Graph"
9. You will be sent to /history.php?...&form_refresh=1&action=batchgraph&itemids...
10. Bookmark this page (or send the url to someone else)
11. Someone loads this page and decides that they'd like to change which graphs are shown

Result:
There's on way to go from here back to the picker to add/remove items.

Expected:
It would be nice if there was a way to go back to a view that had the same items checked (preserving the filters to make it easier to round trip would be helpful, but really, anything to let someone easily add/remove w/o url hacking would be appreciated).

Possible approaches:

1. Have an edit button / link that provided a check box for each row of things shown to let people toggle and then apply (to at least drop)
2. The edit option, plus a filter view for doing adds
3. A thing that takes one back to the Latest data chooser (possibly including including the filters into the graph url)
