lock profile in memory while game is running

so I tend to alt tab out of games to do other things. I seem to recall Synapse 2 having the option to lock the profile assigned while the game was running. I'm not seeing that option on Synapse 3. The scenario is I'm playing Game X, and I alt tab to a browser to look something up, or discord to chat. When I switch back to the game there's several seconds where it's the default profile. I'd just make that the 'default' but I do play multiple games, so it'd be inconvenient to switch it constantly.
