Marketing Channel Processing Rules & CJA

Hello!

We're trying to get CJA setup with Marketing Channels. Currently we have Marketing Channels setup in Adobe Analytics, however, a couple of our channels are setup with the rule "is first page of visit". Updated Marketing Channels documentation has mentioned that is is not recommended to us that logic as CJA does not recognize it. (potentially not understanding that correctly). We have an extensive network of internal URLs for instance that we need a channel for in order to not inflate our direct channel traffic. Is there any suggestions on how we might get around this so that we can see all channels in CJA as well? Thanks!
