maybe there is other easy way
but in one my site i did it like this
i use the title of the publisher page/item
put this in publisher_item.html or company_item.html something like that
try
le="color: #000000"><?php <{if $item.title=='Dr. Gaurav Kulkarni writes about his experience of the hypnosis course'}> <{$xoops_block_125.content}> <{/if}>
i think you get the idea
