@jennifer_dungan Makes sense to me. But If I try to put different values in a list format in a rule then its by default is "ALL" operator instead "Any" and for one rule it doesn't allow you to choose "Any"...
In my previous response where I shared a screenshot for paid social, you saw a list of values with "Any" operator. It came for me when I clicked ADD New rule and removed it. That way I selected "Any"
So I want to confirm from this ASK is if I put values as list in rule and keep "ALL" then my condition will work or not?
The "All" and "Any" in that initial drop down reflects the rules/boxes/blocks in the rule set (the ones that you can remove with the x, or add with "Add rule"):

In this case, in order to be identified as "Paid Search" the channel must BOTH match the "paid search detection rules" AND the "cid" must start with "pad" or "med".
If you change it to "ANY" at this point, then it need to match either (or both, its not an exclusive or) "Paid Search Detection" OR "cid starts with one of the listed items"
This list block is always going to be an "OR" list, no matter what is selected in the All/Any dropdown:

I don't know why you are saying this can only be an "ALL" rules... you should see "ANY" in the dropdown, if you have more than 1 rule in your rule set.....

Unless you removed the "matches paid search detection rules" like so:

But still, the ANY/ALL refers to the blocks, not to the list items... the list would be useless in 99% of cases if it was processed as an "AND"... IF you need something to "contain X and Y" then you would make sure you have "ALL" selected, and create 2 rules:
cid contains "X"
cid contains "Y"

cause you need BOTH to be true... and they are not mutually exclusive.
