Can I combine string resources in xml titles

I would like to combine resource text definitions in the properties.xml settings part to form a logical title.

For example:

            <setting propertyKey="@Properties.gauglesbindinghourshand" title="@Strings.hourshand">
                <settingConfig type="list">
                                [...]
                </settingConfig>
            </setting>
            <setting propertyKey="@Properties.gauglescolorhourshand" title="@Strings.hourshand @Strings.color">
The compiler gives this error:
venu3: The given title resource ID '@Strings.hourshand @Strings.color' couldn't be found in the Rez.Strings resources.
Is there another syntax I can use to make this work, my eyes are squared so maybe I overlooked the obvious, or do I need to define extra string resources?
