Any way to define-once and reuse a colors-palette in settings.xml ?

Hello,

Assuming I have X GUI-elements on the screen/display (e.g. date/time/heart-rate/...),and that I want to let user customize their colors by choosing from the very same Y colors (e.g. red/yellow/...), then I would set my settings.xml as followed:

    <setting propertyKey="@Properties.bgColor" title="@Strings.bgColor">
        <settingConfig type="list">
            <listEntry value="0x55AAFF">@Strings.colorCustomColor1</listEntry>
            ...
            <listEntry value="0x11FFEE">@Strings.colorCustomColor10</listEntry>
        </settingConfig>
    </setting>
    <setting propertyKey="@Properties.dateColor" title="@Strings.dateColor">
        <settingConfig type="list">
            <listEntry value="0x55AAFF">@Strings.colorCustomColor1</listEntry>
            ...
            <listEntry value="0x11FFEE">@Strings.colorCustomColor10</listEntry>
        </settingConfig>
    </setting>
    <setting propertyKey="@Properties.timeColor" title="@Strings.timeColor">
        <settingConfig type="list">
            <listEntry value="0x55AAFF">@Strings.colorCustomColor1</listEntry>
            ...
            <listEntry value="0x11FFEE">@Strings.colorCustomColor10</listEntry>
        </settingConfig>
    </setting>

And the question is whether it is possible to define the colors once e.g. as a palette and then re-use it, instead of repeating the whole

        <settingConfig type="list">
            <listEntry value="0x55AAFF">@Strings.colorCustomColor1</listEntry>
            ...
            <listEntry value="0x11FFEE">@Strings.colorCustomColor10</listEntry>

palette/colors-list over and over again in each GUI-element setting ?
