Test Document with mock-up

This is an enhancement request.

Problem description: 
Current proceeding is rather long winded, please follow description in sample document for WRITER:

Both fields are „Date / Fix, means they show the latest time when the fields have been updated.
To get the current fields you currently need:
1. Double click on field (dialog opens)
2. In middle pane change selection from “fix” to “current”
3. OK (dialog closes, date (or time) changes)
4. Double click on field (dialog opens)
5. In Middle pane change selection from “current” to “fix” 
6. OK (dialog closes)

Suggestion - Add an Update button!
More comfortable way how to update:
1. Double click on field (dialog opens)
2. Click Update (dialog closes and field updates to current 
   time and date

Alternative - It might be more useful (and may be more consistent) not to close the dialog immediately, but to allow to select other fields with next / previous buttons and to close the dialog with OK.
But for my needs it would be more useful to close dialog immediately with Update.

Additions:
The Update function also should be available in the context menu for the fields.
It should be checked for what other fields such an update might be useful
