Special validation value set setting (exclude value and generate range values)

I have custom report named „XX Invoice Register“ (copy of „Invoice register“ report).

In it I have a parameter with value set (copy of standard Oracle special validation value set 'GL_SRS_LEDGER_FLEXFIELD2').

I need to exclude value '9999' from this value set (this value is included in security profile).

Beside this, I need to display only report results based on values provided by value set and not for values between (if any).

For example, if selected value '0923' (as value from) and value '0926' (as value to), report should display only results for '0923' and '0926' and not for '0924’ and '0925’.
