Polymer - items in paper-listbox

If I want to create a paper selector from an array with polymer it looks quite cumbersome:

...
        <paper-listbox
                slot="dropdown-content">
            <template is="dom-repeat" items="[[myItemList]]">
                <paper-item>
                    [[item]]
                </paper-item>
            </template>
        </paper-listbox>
...

Especially it looks like the dom-repeat template is always required. Is there any shortcut like

    <paper-listbox item-list=[[myItemList]]
            slot="dropdown-content">
            <paper-item>
                [[item]]
            </paper-item>
    </paper-listbox>

or does everyone implement an own web component for this pattern that does that?
