Feature Request: Reroll Doubles

[ianfhunter]

Is your feature request related to a problem? Please describe.

In DC Heroes, a roll of 2d10 should be rerolled if the result is 00,11,22,33,44,55,66,77,88,99

Describe the solution you'd like

2d10r!=u ?

reroll when not unique

Describe alternatives you've considered

n could be an inverted u, but I think it will start to become messy
