Sopohos UTM MFA session timeout

We have setup the Sophos UTM from the AWS Marketplace (ver 9.603).  We have configured it with MFA access so that when we connect using the VPN clients we need to provide our MFA code.  We need to do this every time we connect which can be a bit of a hassle for our VPN users.  I was wondering if sophos supports session timeouts when connecting with MFA which would allow reconnects within a timeout without having to enter MFA again?
