Creating a group of people who belong to multiple groups

I have some groups with manually selected people in them and I’m trying to create another group via Boolean rules where IF a person is in Group 1 AND Group 2 they are automatically added to Group 3.

For example, I want to create a group from my living MCRAs who are ALSO interested in genealogy. But when I try to use Group as a rule it only seems to add people in both the MCRA group OR the Genealogy group not just people who are in both groups at once.

Is this possible? And if not, how can I request this feature be added?

Thank you

One approach you might try, using the new rule-based group logic:
rule1 = Select people in Group1 and
rule 2 = Unselect people not in Group2.
With this approach, you would define group 2 in such a way that it’s everyone but the genealogy group.

[edit: you don’t really have to define a group2, just create rule2 so that it’s everyone except your group2. hope that makes sense. The new rule concept is covered in one of the RM10 videos on youtube. I believe it’s the what’s new in rm10.]

A more direct way might be the new Group functions … check under Tools, Group Tools, Combine and manipulating groups…

I find the Group Functions tool to be too manual, even though they do work. I just want to be able to click Refresh to refresh my groups. I don’t want to have to manipulate the Group Functions tool manually. That means that I want all my groups to be Rules groups.

Unless I’m missing something obvious, you cannot do membership in Group A AND Group B directly using a Rules Group. What I do instead is to create Group A as a group and to create Group B as a group and to create Not Group B as a group. My definition Not Group B is to select everybody and then to Unselect based on Group B. With those definitions in place, you can get Group A AND Group B by selecting on Group A and then unselecting on Not Group B. There surely is a simpler way to get this effect that I just haven’t thought of yet.

exactly what I was thinking and going to say. Only should be used for a one time thing

The AND / OR logic of “criteria” and rules could use improve as it can be confusing to get the desired results one is lookin for at times.

Thanks! I didn’t realize this was an option. That was exactly what I was looking for and worked perfectly!
