Keep groups of metaballs separate?

Let’s say I have two separate groupings of metaballs in near proximity, thus group A and group B. However I only want metaballs in A to only react to those in A, and likewise those in B only reacting to those in B. Is there any way to do that?

I’ve tried various ways of separately grouping them that should seem obvious, but to no avail. The metaballs in one group still react to those in the other. Any suggestions?

You have object families controlled by the object name

I was trying parenting, grouping, layers… Didn’t occur to me that the name part in front of the appended digits had to be different. A lot simpler than I thought. :o
