Graeme,

No, you'll need to run something like Tagz first or a couple of "Replacez".

Here's a generic "recipe":

1 Find:
Start of text string

Replace w/Some unique tag:
<starttagz>

2 Find:
End of text string

Replace w/Some unique tag:
<endtagz>

3 Run Tagz, using the start/end tags just inserted to insert another <tagzzz>

4 Run Replacez to replace the <tagzzz> with your new info.

5. Remove your start/end tags used in steps 1 and 2.

While it seems like a lot of work, the truth is this should only take an extra minute or two and this technique can very useful.
