Control group based on custom attribute
Hey everyone! I am wondering if anyone had a similar situation: standard tool for isolating control group (global or Canvas- specific) does not fit my business needs, because I want to measure incremental change of product conversions per B2B subscriber, and each B2B subscriber can have more than 1 employee (aka user ID in Braze). Therefore, there is a risk of having representatives of the same B2B entity in both control and treatment groups. How would you deal with this issue? I have an idea of assigning custom attribute (control_group = true/false) when importing each new user (so that all users within one B2B entity fall into either control or treatment group), but it makes managing campaigns and building reports more complicated.
I'll be grateful for your ideas and sharing your experience. Thank you! :)
