GRE / Centralized Forwarding MTU - Jumbo frames?

We run a sparsely distributed WiFi hotspot network on our own infrastructure which supports frame sizes beyond 2000bytes in all network segments.

Currently we are dependant on using the "Tunnel WLAN traffic through Ruckus GRE" feature but aren't able to set the Tunnel MTU past 1500 or Auto as per the configuration screen.  We'd like to use GRE packet sizes beyond 1500 so that we can account to tunnel overhead and allow for clients to send/receive full 1500byte packets themselves without fragmentation.

Our tunnels to not transit the internet in any way, we have full control of the data path from AP to SZ-100.  The reason we want to do this is that there have been a few customer complaints linked to certain vpn clients not handling MTU very well and exhibiting tunneled application connection issues when not able to use a full 1500B.

I know it's the client's VPN software issue but, they're still the client and we need to cater to their needs as best we can.

If you support jumbo frames throughout your network infrastructure, you do want the tunnel MTU increased, but if the SZ-100 screen won't let you, please open a ticket and request a bug be submitted.
