How to limit the AOR of a unit?

[Atraphoenix]

I need to learn how can I limit the AOR of a unit under current recruitment system of EB.
For example what must I write for :

recruit "roman infantry legionary cohort i" 0 requires factions { seleucid, } (for Dalmatia)

I know EB has a very complex AOR system
How can I get the hidden resources? or how can I learn how a city determined via hidden resources?
In EDB the hidden resources are given but I do not know which cities have them.

hidden_resources rome sparta italy desert tradeport navyport bigport not_here nomad mixed river gallicport smallfleet variantro variantgr variantba variantno variantca varianteg variantea EA SW NW A B C D E y1 y2 y4 y8 n1 n2 n4 n8 homeland pahlavahome noroads nopavedroads persia

Plus how many hidden resource can I add? or how can I add?
I am sure it not simple just like:

hidden_resources rome sparta dalmatia
recruit "roman infantry legionary cohort i" 0 requires factions { seleucid, } and hidden_resource dalmatia

Thanks beforehand

The descr_regions.txt in the map folders will list what hidden resources are placed in a given settlement. I posted a map in the map thread with the hidden resources, however you have to understand the binary to read that map.
