Superscript in auto correction, is it possible?

Hi all,

we recently rebranded our company name and now our last two characters are in superscript, eg. they sit higher off the line in a smaller font. Now I can type the company name ABCSS and highlight and make the SS part superscipt and all looks good but how can I make this automated? Is it possible, is it possible in a mail template change?

Any help gratefully received.

Thanks
