cautious update of variables – best approach?

[FieryPantone]

So ... I have a stack of user variables, some of which keep the same value in every chapter while others are manually adjusted. File > Import formats from a "good" file will trample on the manual variables in the others. Short of setting up a quick todelete.fm with just the one user variable I want to flood through the book, is there an easy way of updating just one? I suspect "plugin" may be the answer <g>

Niels,

How about Mif snippets, e.g.

  <MIFFile 8.00>

<VariableFormats

<VariableFormat

   <VariableName `MyVariable'>

   <VariableDef `Some product name'>

  > # end of VariableFormat

> # end of VariableFormats
