We have Account records that we use for clients, and for channel partners (who sell to clients).

We have two attributes for channel partners - let's call them type A and type B. A channel partner can be a type A, a type B, or both A and B.

We have some fields that we only want to show for type A partners, and some only for type B. No problem - we have a Layout Rule for each of these, selecting the appropriate fields.

But here's the problem. We have some fields that we want to show if the Account record has either of the channel partner type fields checked. I can't work out a way to do this.

I can't select a field to be shown in both Layout Rules - once it's selected in one, you can't select it in the other.

And I can't use a formula field (where the formula is "type A OR type B") as you can't use a formula field as the selector for a Layout Rule.

Any bright ideas?
