Taxonomy / terms vars templates

Hello,

with Bootstrap we have the block.vars.php file and page.vars.php file for customize functions for the pages and blocks.
But for create preprocess functions for the terms and taxonomy we have no base file for include custom code.

For this time I place my code in the template.php.
But, Is there a file for customize functions for terms and taxonomy ? (e.g. : taxonomy.vars.php , term.vars.php...).

Thanks.
