I couldn't quite get comfortable doing this myself either, always having to hold down the space bar whenever I moved my team. Instead, I just hold down the left mouse button for that. I click in whatever direction I want them to go and hold it until I want them to stop, just moving the mouse around to steer them, which works well for me.

I do however have the A, S, D and F keys bound as the Force Move keys for my four character slots respectively, so when they desync for whatever reason (e.g. one gets feared), I can hold down the key for that specific character and move them back into the fold. To me, that felt more natural than always having to hold down a key to move. I mostly just nudge them into corners still of course, but for individual and/or mid-fight adjustments, that often does the trick for me as well.
