Not Enough Tiers in Gateway Group

[break1146]

Hello all,

I've not run into this issue yet, but it's very likely I will in the near future. The priority selection in Gateway Groups stops at 5 tiers, but in this case I would have more gateways that I want to apply sequentially.

Obviously most gateways won't actually be doing much, but since there is different costs involved with them, we want to address them in a specific order.
(I'm aware I can just apply different groups to sources with different needs. But some would be allowed to access everything so to speak).

Does anyone have ideas, maybe something I've overlooked here?

Thanks!
