Modifying an existing preference - prefix or suffix some content

[peterkir]

Hi oompher,

I would like to know, if it is possible to modify an existing preference value and re-use the existing content.
e.g. prepend or append some content

Not really. It would seem kind of tricky too, i.e., how to avoid adding the prefix to the already-prefixed value?

Probably there would need to be some new type of task that could use a pattern to match a preference's value and would able to replace the value if it matches the pattern; then one could use captures in the replacement. A little like what's possible with a Text Modify Task...
