Batch updates

Hi all,

I am working on an existing website in DWMX and was wondering if it is
possible to do batch updates.

The scenario is as that the exisiting site (about 600 pages) was
originally crteated with DM4 and utilised templates. The new site is
being updated, again using templates. I have maintained the same
editable regions.

I know I can apply the new template individually but was wondering if I
can automate the provess. Don't look forward to upfating som many files
individually.

Thanks for any help you can supply.
