Controling the Max Number of Replicants

System

On 5.5.2 SP2

Looking for a solution to dynamically change the max number of rerplicants depending on the value of a radio button on the DCT. I've gone down the path of making the individual replicants visible/invisible along with setting their value to empty string, but I'm not crazy about that solution. I'd rather directly affect the max number of replicants and have any existing replicants, that are over that max, disappear.

Any thoughts or ideas?

Thanks,

Jason
