Accounting zero using custom format option

As of right now I created a custom format for my 1000 to show up as 1k and my 1,000,000 to show up as 1.0m

Now the issue: How do I create a template to where my 0 shows up as (-) instead of (k)

Here is the formula

[<=-1000000]"-"$*(#.0,,"M");[<=0]$* (#,"K");(#,##0.0)

All help is greatly appreciated!

I need the negatives to still show as a negative number not a -(-). But thanks for your attempt!
