*$:/config/SaverFilter *defines a filter that determines whether or not the
isDirty flag is set.
When you export tiddlers, you could add those tiddlers to
the $:/config/SaverFilter definition, thereby allowing those tiddlers to be
ignored when exiting, bypassing the warning. Of course, you'd also want to
add -[[$:/config/SaverFilter]] as well, so that the changes to the filter
itself won't trigger the warning on exit.
Add something like this to your custom export button:
\define newItem() -[[$(item)$]]
<$button> custom export
... do your custom export processing ...
<$list filter="... stuff you've just exported... " variable="item">
<$action-setfield $tiddler="$:/config/SaverFilter" text={{{
[{$:/config/SaverFilter}addsuffix[ ]addsuffix<newItem>] }}} />
</$list>
<$vars item="$:/config/SaverFilter">
<$action-setfield $tiddler="$:/config/SaverFilter" text={{{
[{$:/config/SaverFilter}addsuffix[ ]addsuffix<newItem>] }}} />
</$vars>
note: untested code
Hopefully this should get you most of the way there...
