Mode-button on map2n?

Hi,

I noticed in recent releases of RouterOS there is a /system routerboard mode-button menu where you can set a script to run when the mode button is pressed
This doesn't appear to work at all on my wap2n and if I enable it then do a print/export nothing is exported
It would be nice if this could work
[admin@MikroTik] /system routerboard mode-button> set enabled=yes on-event=script1
[admin@MikroTik] /system routerboard mode-button> print

[admin@MikroTik] /system routerboard mode-button> export
