Rex Level Breeding

[DavidRexBreeder]

Max bred rex level can be no higher than 379 as +71 levels to max level = 450. Any rex over 450 is deleted from server when the server is reset.

How can I set the Stat Calculator to only show breeding pairs that will produce babies no higher than 379?

I know that I can add importance to the stats I am interested in with the Stat Weighting but there is no weighting for the level, just the graph at the bottom showing probability of levels.
