How to, prevent mozc from suggesting conversion of 'sa' / さ to Kanji?

[octimis]

I'm aware this can be 'temporarily' avoided by pressing enter key instead of space key. But I'm if this 'suggestion' can be disable for specific characters, instead of inverting/swapping the key settings (set space to enter and set enter to space).
