Wildcard address

Hello all, Perhaps someone can help me with this issue, i' m currently replacing some Cisco ASA devices with Fortigate 100D and i have some trouble getting wildcard addresses working. The situation is as follows: there are some 23 locations in the organisation, every location is defined by the second octet in the IP Address, every location uses an exact copy of the VLAN definitions so the third octet show the role of the subnet. e.g. 10.101.1.0/24 is in fact location 101 and subnet 1 (workstations) and 10.102.1.0/24 is location 102 subnet 1. the rights assignment is identical for each location per subnet, so subnet workstations is allowed to pass HTTP/HTTPs unrestricted but subnet 2 is only allowed THHP traffic to specific hosts. on the ASA devices this is very easy to implement using a wildcard mask and creating a network object like 10.0.1.0/0.255.0.255 this allows for a single line/networkobject to be applied for all locations. on the 100D devices this seems impossible, the documentation does speak of wildcard possiblilities but if i enter a network object like set wildcard 10.0.56.0 0.255.0.255 it ends up as set wildcard 0.0.0.0 0.255.0.255 in the config and the GUI page Firewall Objects > address > address remains completely blank until the line is removed using the CLI. this kind of scares me to think that on both devices i need to manually add all these subnets for all locations, due to the amount of diferent combinations (all repetitive) this is prone to configuration error' s. Maybe somebody can enlighten me if this realy is impossible or perhaps offer an alternative option. thanks in advance.
