Card Reroll Sets

At this point in the game cycle we can really only use 90+ OVR cards in sets. Can we please get a higher quantity reroll option? Instead of 4x 87 to 1x 89 could we get a set for 12x 87 to 3x89? We get these lower overall cards as rewards from the xp path, ranked and champs but the time it takes to reroll hundreds of these is absurd.
