TYPO3 Core

If i want to create an link in lets say TextMedia, i mark the Text and create an link. In this Pop-Up where i can set title, path and target i get my default values in the first tab, sites. If i now switch the tab to external links, there are still the default values from the sites link. In the core there is an if witch checks if there is already an value in title an if, then it doesn't overrides them. Just if the title is empty it sets the default values wich i defined in typoscript for the ck-editor.
Could you build in the option to make this query editable, so that there are two options:
1. on tab switch it doesn't overrides the values and fills the default just if the value is empty (current).
2. on tab switch all values will be reset to blank and then filled with the default values from the ck-editor/typoscript (like in the older Typo3-Versions like 4.5).
