How would you better represent this relationship

Assuming I want to add more fields based on the value of Range

#[derive(Subcommand)]
pub enum SubCli {
    #[clap(name = "add")]
    Add {
        /// How should we allocate funds
        #[clap(long, default_value = "constant")]
        strategy: AddStrategy,

        /// How does the range get determined
        #[clap(long, default_value = "PriceSpread")]
        range: Range,

        /// The amount of base token value to add in USD
        #[clap(required_if_eq("strategy", "lopsided"))]
        base_value: f64,

        /// The amount of quote value to add in USD
        #[clap(required_if_eq("strategy", "lopsided"))]
        quote_value: Option<f64>,

        /// The amount of value to add
        #[clap(required_if_eq_any([("strategy", "constant"), ("strategy", "normal")]))]
        value: f64,

        /// The number of positions allowed
        #[clap(required_if_eq("strategy", "normal"))]
        buckets: Option<usize>,
    },
    /// Spawn a tui to interactively remove value from postions, or pull all
    #[clap(name = "remove")]
    Remove {
        #[clap(long)]
        all: bool,
    },
    /// Get ranges according to some strategy
    Range { range: Range },
}

#[derive(ValueEnum, Clone, Copy)]
pub enum AddStrategy {
    /// Create two positions, one for each token around the market price according to some range strategy
    Lopsided,
    /// Create a position with a constant value across the range
    Constant,
    /// Create a position with a normal distribution of values across the range
    Normal,
}

#[derive(ValueEnum, Debug, Clone, Copy)]
pub enum Range {
    /// Create a range from the current market price
    PriceSpread,
    /// Create a range based on volitiality trends
    Volatility,
    /// Create a range based on mean reversion 
    MeanReversion,
}

So it looks like you have a number of arguments that require specific values from strategy but its fine to include them if the specific strategy is not set? And you want to do similar for range?

ahh actually I would prefer if they couldnt do that! Im sure you can accomplish it with another command but i almost feel like im looking for nested subcommands

This seems to be what im looking for
