Any way to use 'this' (or another keyword) to refer to the innermost nested objects?

Question

My code needs to handle several scenarios that involve importing specific files. The info for each scenario is stored in a JavaScript object. I would like one property to reflect the import filename and another property to reflect the import filepath. I also want to avoid having to update the filename in two places each time I create an object for a new scenario

Current Setup

    // Cross-Scenario Variables
    static inputFolder = './resources/xl-data/'

    // Import Scenarios
    static scenario = {
        scenario01: {
            scenarioDescription: "Scenario 01",
            importFilename: "scenario01.xlsx",
            importFilePath: this.inputFolder + "scenario01.xlsx",
        },
        scenario02: {
        },
        // etc
    }

Ideal Setup

    // Cross-Scenario Variables
    static inputFolder = './resources/xl-data/'

    // Import Scenarios
    static scenario = {
        scenario01: {
            scenarioDescription: "Scenario 01",
            importFilename: "scenario01.xlsx",
            importFilePath: this.inputFolder + **this.**importFilename,
        },
        scenario02: {
        },
        // etc
    }

I am already using the 'this' keyword to access a global property. Is there another keyword I could use to refer to the innermost of several nested objects?

I want some way to refer to the importFilename property from inside of the scenario01 object.
