Supply value as a string rather than an object

I'd like to be able to use `:selected-option="value"` where `value` is just the value for the select, rather than an object with the text + value. 

Currently I have to store both the text and value in a cookie in order to correctly pre-fill the select on next page load. This is frustrating when `text` for that value could change over time and would therefore fall out of sync with my cookie.
