differenent values for 'label' and 'value'

Hi!

Is it possible to define differenent values for ‘label’ and ‘value’ for radio buttons?

eg.

<input name="region-333" value="categorynr1" type="radio">
<span class="wpcf7-list-item-label">Category Nr 1</span>

Reason: I’d like to use the ‘value’ as part of the e-mail-adress where the form is sent to.
–> “<categorynr1@mydomain.com”
This will not work with “Category Nr 1@mydomain.com” due to spaces and capital letters.

Thank you!
Irene
