if fortimanager with the work

We have about 10 sites, each with a fortigate. VPN connections back to main hub. Starting to add fortiswitches.

Trying to config and use fortimanage. But it seems things i can do in a second on a fortigate takes minutes in manage. Sure somethings may be easier like running a script on all units or updating firmware. But day to day tasks just seem like more work. Or does it just take practice
