Can't give monk more than four attacks

[Callum]

One of my party has a monk who has just gone up to 11th level, so he now has five attacks using flurry of blows. However, on the character sheet, on the Actions tab, there are only four boxes under "Attacks", and it doesn't appear to be possible to roll the number in the "#att" box up above four. Is there any way to give this character five attacks (and then six and seven, at later levels)?

It would require an extension to modify the ruleset to do that.

What I did for a monk in my campaign was just to set up either a second weapon entry for remaining attacks; or if it only ever is 5 attacks and the first two are the same bonus, then just set up with 4 attacks and have them roll #1 attack twice.
