I don't know an easy & pure Typoscript solution.

Maybe you can use the userfunc of the value modifications ":="-operator
http://typo3.org/documentation/document-library/core-documentation/doc_core_ts/4.1.0/view/1/2/

use the hook to call a userfunc:
$TYPO3_CONF_VARS['SC_OPTIONS']['t3lib/class.t3lib_tsparser.php']['preParseFunc'][$tsFunc]

I am sorry, but I cannot give you an example how to do that exactly. 
Take it as a starting point.

But maybe there are smarter solutions?
