[TYPO3-dev] Flexform - Inherit Typoscript setting if empty - store null value

[Philipp Wrann]

I was wondering if this is also possible in flexforms:
http://docs.typo3.org/typo3cms/TCAReference/Reference/Columns/Input/Index.html#columns-input-properties-mode

Would make some things a lot easier.

I am searching for an option to make it possible to save null in flexform and in case the configured typoscript setting should be used as a fallback.

Is this possible?
