Ipsec remote access VPN question

We have a business case to use 2 seperate Remote Access VPN configurations on one Fortigate. We have a 50 FortiClient license for our corporate laptops with full access to the network services. With the current COVID 19 situation we are  looking into allowing users using their home computer with the free FortiClient VPN to only access RDP services for remote desktop.

I have tried to create a second Remote Access VPN (Different Shared secret and source IP range) on the same untrust interface, but that one got precedence over the other and people couldn't use the original VPN anymore.

Is want I want even possible? 

Thanks
