Better way to send commands with change checking

My Update loop is flooded with stuff like this:

Code (CSharp):

1. if (isFireingMissile != isFireingMissileChanged) {
2.                         CmdSyncIsFireingMissiles(isFireingMissile);
3.                         isFireingMissileChanged = isFireingMissile;
4.                     }

So for every bool I want to send to the server I have to make two bools and check for change. Maybe I'm overseeing something in the docs, but Is there a better way to prevent commands from being send when nothing has changed? I know Syncvar is doing this automaticly but from the profile I see that the command is executed, regardless of a change in their parameters
