Static Routing across Site to Site VPN with many remote subnets

Relatively new to Palo and I feel like I've spent hours searching with no answers so, if this is a completely basic topic, please feel free to point it out.

I'm migrating a dozen or so firewalls from FortiGates to Palo PA-445 (using Panorama). My company uses a lot of site to site VPN's and many of those VPN's have dozens of remote subnets defined. The remote subnets are rarely contiguous and frequently are a bunch of /32 addresses. In FortiGate, I can just create a 'Remote Subnets' address group for each tunnel and assign that group to the static route that uses the tunnel as the target. In Palo, I can't find a way to use any sort of a group. I have no control over the remote side of the tunnel and can't guarantee any sort of routing protocol could be turned on (I can probably guarantee it won't be) so any config needs to be done on my end.

Do I really need to create hundreds of individual static route entries in order to get this done? I haven't enabled Advanced Routing because I don't really need it (unless I do for this) but it seems like this is a crazy amount of work for something that should be so simple.

Am I completely off base and missing the obvious? Any tips would be much appreciated. Thanks!

@K.Saucier,

The destination can only consist of address objects unfortunately in PAN-OS. It may be faster for you during initial configuration to actually perform this work in the CLI/XML/API than through the GUI where entry is a bit tedious.
