theme taxonomy_term-select based on $node->type

4.7.3. I am developing my first node type module and wish to display the categories side by side instead of vertically. I got this working by putting a function myTheme_taxonomy_term-select($form) in template.php in my theme folder.

I would prefer that this altered display applies only to my new module, not every usage of taxonomies.
My new module has two required vocabs but a "Page" node is likely to use only one. This breaks my current themeing, as it hard-wired to a two cell table to get the horizontal display.

The taxonmy_form_alter hook treats all node types the same (understandable).
Is there any way I can theme taxonomy_term_select based on $node->type?

Thnx Paul
