Delete Device data by time period.

Currently, the delete action in Locations panel will delete all that device data.

On the confirmation modal dialog, I'd like a checkbox:

• [x] Delete selected dates only
• [x] Do not reload Companies on each device change (when that does not needed)
• [x] Add persist support for checkboxes

Sometimes I simulate location and I want to destroy only a selected block of location data (start -> end date) and not the whole device:

I think it can be closed. Or I'm missing something?
