Are there any options/prefs/tools to prevent automatic operations in
PowerPoint?

Examples of problems:
- copy-paste of picture resizes automatically all images, also a title pop up
- paste special of text always starts with HTML format. can it be changed to
start with any of options e.g. Unformatted text?
- text boxes act in very confusing ways: when typing more text the box
sometimes does not extend downwards, sometimes it extends upwards (cursor
position staying stable)
- saving file should be predefined to open e.g. a certain folder. Now it is
always the last one saved.

I would like to define my own preferences to above mentioned topics. Is it
possible?
