Send SMS to Work phone number?

[wirecutter]

I have some Contacts who have cell phones for work. So I list their work cell phone numbers as their 'Work' number in the contacts. The phone won't give me these 'Work' numbers as options when adding people to an outgoing SMS. Is there a way around this?

Basically some people I know have more than 1 mobile phone, but windows mobile doesn't let you put in more than 1 mobile number...and the SMS app only recognizes 'Mobile' phone numbers.

Thanks.
