Preview Tokens in A/B Subject Line Tests

It would be really helpful to preview tokens in A/B subject line tests.

I like to actually test every email that goes out (especially when using tokens). There appears to be no way to actually preview tokens in A/B subject line tests today without making a copy and sending a live version of the email to a seed list (which should be reliable, but still leaves things to chance since you're sending a copied version).

It would be good to actually be able to preview token's in the A/B test panel the same way you can in preview -- or be able to send tests of both A and B.
