Azure P2S connecting to remote VNET over Global Peering

Hi

I have a scenario where by I have two vnets in two different regions with global vnet peering enabled and functioning correctly as i can ping from a vm in vnet01 to a vm in vnet02, 

Both vnets contain a VPN Gateway so I cant use “Allow gateway transit” 

if i connect to the vpn gateway in vnet01 via a P2S VPN i can ping vnet01 VMs but not VMs in vnet02,

if i connect to the vpn gateway in vnet02 via a P2S vpn i can ping vnet02 VMs but not VMs in vnet01,

Ho do i allow P2S connections to connect to their home vnet and then route to remote peered vnets?

I have looked at this doc below but it doesnt match my scenario as i ahve a GW deployed in both VNETs and I need this as i ahve to ahve P2S and S2S VPNs in both VNETS 01 and 02

Thanks in advance
